#and thus they have familial reunions on a giant warm rock Rhea magically warms

[randomnameless]

AG AU where Billy is recruited, ignores Jerry and hangs out with those people who look like the gremlin in his head (who apparently logged off their mind otherwise the plot wouldn't work).

The shady lady Jeralt always told them to watch out for has a strange hat, but she talks to them and even said she enjoys spending time with them, even if they don't say a thing or eat a strange fruit together. Sometimes she talks about their mom, a woman called Sitri, and recalls stories and anecdotes and Billy feels closer to the mother they never met than to Jeralt.

(then Billy felt immensely wrong and guilty, because they are the reason why Sitri isn't alive anymore and is it their fault? Jerry drunkily said Sitri died to birth them, it's as if they killed her :( - the shady and evil lady then hugs them - it's so awkward for the both of them but Billy feels so strange and they hug the evil lady back, crying for the first time, and they cry even more when the evil lady tells them Sitri would never have wanted them to feel sad about her fate because she chose their life over hers (she still doesn't tell them about the magic rock).)

The young lady who loves to talk about romance and to ask them how was the world they saw was saddened when they told her they don't like to be called Ashen Demon - so she calls them Billy, and gives them a new nickname : "Big Tuna", because they can catch a lot of fishes.

Billy found this nickname so ridiculous, but was happy to have something else, that they laughed, and from now introduced themselves as "Big Tuna".

The "not-fun" man who always frowns, well, frowns but often asks them to help him "supervise" stuff here and there - but he is different from Jeralt, because when Billy does something he thanks and congratulates them - saying it is important to convey his gratitude for the help he received through Billy's actions, which leaves Billy puzzled - what even are thanks? They grow more and more puzzled when some randoms, from kids to knights to monks to random persons thank them, and they finally ask the "not-fun" man if they could continue making people smile after the war.

Seteth is surprised, but nods : if they want, when the war will be over, they could join a place called Garreg Mach, to help and make people smile all around Fodlan.

(Jerry returns from a two weeks long mission, and sees his kid eating an inedible fruit with Rhea and her clique, sitting a on magically warmed rock, and now Billy call themselves "Big Tuna" and say they want to make people smile by helping not by killing anymore, just like their Mother did before, and even now after, her death.)

Post AG when the war is over : Billy joins Garreg Mach and learns Faith magic to heal people (without charging them a fee!) and becomes the fishing instructor of Garreg Mach, thus becomes popular with the students who leanr how to focus and how "it is important to rest. And please, try not to drop your belongings on the floor."
