In the episodes final moments, and one of its most WTF happenings, were reintroduced to the familiar face of Harrison Wells. Sure, the opening credits may have totally ruined this surprise for some by name-dropping Tom Cavanagh, but it was still great to see the always-engaging Wells appear on screen. Of course, this is seemingly the Wells of Jay Garricks world, so that throws up plenty of questions. This is clearly a Wells who still has the use of his legs, but does that mean that hell also have not met Eobard Thawne? And even if he hasnt met Eobard and been influenced by him, whos to say that Wells himself may not now be a bad guy? Or maybe Harrison Wells really will be the genius do-gooder that was envisioned at the start of The Flashs first season. After all, this is a man who is reintroduced to us here as the saviour of Central City. Then again, the ominous way that Wells says Hello kids is just a tad creepy. What moments from this week's episode had you saying WTF? Any we've missed? Let us know in the comments.
