That argument alone doesn't make sense, because Engel and Claire is shown to have some connection (even outside FPE cause BiB animation isn't canon). Which means they're most likely peers and makes Engliver 2x times weird
Oliver and ∆lice's age is one of the things that was actually confirmed by Katie herself. And you cannot change people's view at Engliver by saying "oh but Engel doesn't have a canon age!!" Then why would Katie make Claire blushing in front of Engel if she's literally 15?
