#granted if Ionius didn't nuke her family the second her dad died Mercie von Martitz would still have been able to bake those sweets

Hm...

In one of her Nopes expedition lines, Mercedes says this :

"Both of my parents were great cooks. I even remember them teaching each other recipes when I was young. Cute, don't you think?"

Which is pretty odd, because I'm sure it references this line from FE Heroes, where she reveals she special sweets are made using her biofather's recipe, how he taught said recipe to her mom, but more importantly, how he died before her birth so she never saw him !

I told you before this recipe was passed down in my father's house. Before I was born, there was strife in the Empire, and he was killed. My mother and I lost our house and title. I didn't have any keepsakes of his. I had never even seen his face. All I had was this recipe he'd taught my mother.

Now, I would usually take Nopes over FEH in canonicity, but given how both Mercedes and Emile's recollection of Baron Bartels are, I doubt he is the one who was taught and taught recipes to their mother, and she wouldn't call any of their interactions cute!

So obviously, the "parent" who taught her mom how to bake sweets (and who was also taught how to cook too!) could only be Baron Martritz, a man Mercie never knew... and so, she couldn't remember a time where he and her mom were cooking together?

So unless Nopes suggests it's her Faerghan dad (the one who sent her to GM and wants her to marry) who cooked stuff, it's another case of Leopold "I have a major Crest of Cichol and a holy loincloth to prove it!" von Bergliez retcon.
