The Flash Season 3: 9 Big Questions We're Asking After 'Magenta'
4. Is He Going To Find Out About Barry Soon?
Aside from his own secrets, the other element of intrigue when it comes to Julian Albert is his deep mistrust of Barry. We don't know all their history, since we're seeing this from Barry's fresh perspective, so maybe various things have happened to cause this. Unless it's because he too has a name that's comprised of two first names, and thus he knows such people cannot be trusted.
But since he's got both such a sharp-mind and deep suspicion of Barry, it'd be strange if he didn't find out Barry is the Flash, or at least start to suspect as much.
I don't know what'll happen when he does piece it all together, but we could have a scenario where they're both trying to keep their identities from each other. Either that, or it all comes to a head at some stage.
