We've gone two episodse of the Flash this season and we haven't seen Harrison Wells (Tom Cavanagh) of any Earth. Last season ended with Barry (Grant Gustin) saying an emotional goodbye to everyone and asking them to help pitch in and take care of Central City in his absence. And we return six months later to find that Wells and Julian (Tom Felton) aren't around. So much for helping out.
The trailer for next week shows that Wells is back and Michael Ausiello of TVLine give us an idea of just how he returns. Earth-2 Wells, or rather Harry, shows up bearing bad news. No idea what that news is, but he gets a very chilly welcome. He ends up diving into the team's latest case and uncovers a 'literally' big clue into what has created these new metahumans like Kilg%re.
Two of the interesting terms used in his description was "chilly" reception and "literally big". Chilly makes me think of Killer Frost who Caitlin (Danielle Panabaker) seems to be having some issues keeping contained again. The other comment doesn't necessarily bring anyone to mind, but there are some folks with size changing abilities that might be referenced. But what could the bad news be?
The Flash airs on Tuesdays at 8 PM on the CW.
