most people are saying it's the clark kent/ superman effect (comic book makeup ideology), but this seems pretty cheap to cover up a loophole don't you think?

sure, but i feel that the idea of appearance/ makeup is an underwhelming and cheap alternative to the other theories that fans have been coming up with, it's just such a trap for a loophole :(

exactly, this is irking the hell out of me, how would Wells not realise that the crimson comet on Earth 2 looks like a well known serial killer??

time remnant theory

Can someone explain to me why Wells couldn't recognize Jay as Hunter Zolomon the well known serial killer when he was the flash in Earth 2? You know, since they have the same face?
