#(except her fear is actually *quenched* in the episode and she's given a sense of relief instead)

[mc-critical]

E22 is certainly all about the deepest fears and suspicions of the characters related to belonging (or rather, NOT belonging) that accumulate through the whole episode (as it gets more and more likely for them to be fully realized), which in turn makes the jealousy and/or resentment within these characters grow.

Ibrahim starts off still ruminating on Beyhan's words from a previous event relayed to him through Hatice in the previous episode, so his fear is immediately established: the fear of his death coming forth regardless, and from the sultan's hands worst of all; of his place in SS's heart, in the family's hearts, ultimately always ending up shaky and temporary; of him being discarded and erased at a moment's notice; of him never actually meaning anything to anyone, thus he aims for the biggest sense of belonging out of everyone else here: SS is most valuable to him, of course, as this is his first bond in this foreign world, but that value and his approval also turn out predicated and empowered by the value and approval everyone else gives him too. As it all begins from the possibility of a future action of SS and his bad mood that could possibly mean anything in the next day, then it goes to Mustafa's opinion on Ibrahim's closeness to SS, and then it circles back to SS again as a reaction to Mustafa's reaction (hence the smallest recurring disapproval, as Mustafa's stance here is a continuation of Mustafa's remark in E03, means wide disapproval — this is why in Ibrahim's dream everyone is out there witnessing and almost delighting in his execution; even Hatice who is clearly sad, is portrayed with resignation, as if the execution is an inevitablity she has to accept and never go against - this is of course also informed by what Ibrahim has seen of Hatice so far, how she couldn't oppose SS's decision to marry her to Mehmet Celebi even though she loves Ibrahim and aches inside and always claims to not be able handle it if she loses him, so the only thing he can say and do is try to spare her the pain). Ibrahim has to fully belong in order not to be reminded of what he's lost before and what he can lose now, but his sense of belonging is so fragile that every little thing can create big, irreparable cracks, bringing him to realize that he never actually belonged anywhere and what's more striking, he has nowhere to belong now as he's lost everything. This is terrifying to him and he can't share it with anyone (not even Hatice could really provide him solace: she calmed him down a bit, sure, but she also related to Mustafa's motives - right on par with Hatice's theme of relating this episode - that perhaps meaning to Ibrahim that even she can't be reliable, that even she could turn her similar possessiveness against him, if she can muster to do even that), so he buries it deep - he is the only one who doesn't lash out due to his fear in this episode, but this sense of fear beginning with him colors the whole rest of the episode and remains an omen of what's to come next. It's this fear that will make him more offensive, more insistent to secure his position even more and remove everyone who stands on the way of that, even in this season finale.

Mustafa's fear is established by one event in this exact episode that puts him at odds with his brother more directly than ever before (there's a reason why this is their first lesson together): the fear of him not becoming a padişah; of him being replaced by someone else, and by someone else who he too loves worst of all; of his efforts not being recognized; of his father leaving him behind forever, not wanting him, not loving him anymore; of him not having the future he's been eager and preparing to have, what's his use if he doesn't have it?, in that case the only thing he can do is disappear, thus he aims for a narrower sense of belonging: he cares about the rest of his family, but his father's love matters to him most of all. He looks up to him and is inspired by him, trying his best to follow his example in order to be the best he can be. And he is constantly encouraged by everyone to be the best he can be, so when even the smallest threat to that come up, his whole self is challenged, so what's left is to lash out, to defend his beliefs and mindset, to make this fear known in order to evade it. He doesn't belong without his father's love that gives him all he craves. He can't belong if that isn't there. And his belonging predicates on him being prioritized at all times, as this isn't a place reserved only for him, it turns out; anyone can take it away. So Mehmet's assertion plants this fear, while Ibrahim's place next to SS confirms it (Mahidevran here, just like Hatice with Ibrahim, tried to comfort Mustafa by putting Mehmet's words into context as well to an extent, but Mustafa actually managed to ease up until the Ibrahim matter popped up), so Mustafa's reaction is precisely that kind of lashing out. The lashing out culminates the episode but there's some finality attached to it as well, as it is the last such clash Mustafa has with Ibrahim (with him realizing his mistake afterwards) - from that point on, they will fully be a source of support for one another. Even his jealousy of Mehmet that sets up the future becomes more restrained.

Gülşah's fear is established by a series of events in this exact episode, feeding into each other and fueling her at every turn: the fear of falling into disgrace alongside with her closest person, or on her own worst of all; of being scolded by both the person she loves and the person she hates; of being mocked and ridiculed; of being denied the agency to do anything about it, as everyone else overpowers her either by being above her or simply being the majority. Her fear seems the most driven out of self-preservation, not so much out of a desire to belong at first, however these two are interlinked for her as well. Her very survival is predicated by the most narrow sense of belonging: on her sultana, the only person who can give her any sense of belonging. Her job is being next to her, so she has to share her joys and sorrows, but she also gets her sense of respect and worth namely from that role, so she can't help but make these joys and sorrows her own. E22 is the first time this is challenged however, since we see her outside of her sultana for the first time, as even what she has to do due to her role as her servant (taking Mustafa from the lessons and defending him) and as a servant in general (bringing Mehmet to Hürrem), is challenged and that whole facade of respect from others due to her sultana is fully broken (even Nigar's threats and almost drowning Gülşah before are because of something Mahidevran's ordered and done, this here has next to nothing to do with Mahidevran) and then her own wishes to seek justice and accountability are uncovered, but the more her sultana seems to not join in, the more Gülşah loses every sense of belonging in each moment (the mockery of the girls of the harem is only there to accentuate that loss and reveal how alone she is) and the only thing she can do is desperately tie them to her sultana, to cling to her in order to convince herself of her righteousness, of how she hasn't lost her sense of belonging actually, isn't that right?? She has no choice: the disillusionment, the resentment only grow throughout the entire episode and she can't really share the full extent of her sorrow with anyone - even her sultana wants her to suck it and wait, but she's sick of waiting, of being humiliated, so she provides the final imminent lashing out of the episode, the one that sets up the future the most in terms of Gülşah's relationship with Mahidevran, as well as it sets up the main deal of the very next episode.
