I thought this too you can see how jealous of and unhealthily obsessed E2 is with E1. E2 comparing himself to E1 constantly and always trying to compete. It’s one thing to be close to a sibling and look up to them but in this case it’s strange and too much. It makes me concerned for when E1 goes through puberty aswell as other girls around her age cause how will E2 react to that? E2 has been made to believe he will go through the exact same things as Emilia so how the poor kid will find it hard when he realises that’s not the case it’s much harder and more complicated than E2 realises cause his selfish parents have treated this whole situation as an exploitive game when they’ve messed with E2’s mind.
I don’t know if E2 is genuinely trans I’m not inside the child’s head but judging off of everything the last few years I find it hard to believe this transgender situation is genuine I have a lot of doubts because E2 seems quite confused a lot of the time and saying things like he’s been convinced that’s how he should feel or what he should say. I see a child who’s probably grown up feeling insecure and left out looking at his confident older sister with all these friends , fits in anywhere she goes and got attention easily and maybe E2 wanted to have all that too and saw being a girl as a way to be just like Emilia.
