The week is finally here! With the latest trailers for the epic cross-over event (see the two videos embedded below the article), we finally have some footage showing us how this event is going to work, and what the feel of the episodes is going to be like.

It seems there is going to be some Ollie training Barry moments, and they are definitely going to play up the rivalry between the two heroes and their teams, especially with the big question of who would win in a fight, a fight which we actually saw some footage of in both of the trailers.

Also prominent is the difference in style between the two heroes, as both trailers prominently feature the Arrow torturing a man for information, something which Barry does not seem at all comfortable with, especially since his team always manages to figure things out scientifically. (Little does he know of Dr. Wells’ dark side, and how he is in every way so much worse than Ollie has ever been in his pursuit of justice). However, the S.T.A.R. Labs team does come in handy in advancing the ‘Arrow’ storyline it seems, as ‘The Flash’ star Danielle Panabaker (Caitlin Snow) said in a recent interview that “Felicity comes to Caitlin for help with the Canary murder,” a fact backed up by “Arrow”executive producer Marc Guggenheim who has also stated:

“There is a major step forward in the Canary mystery. We have the folks at S.T.A.R. Labs in Central City, and they’re pretty scientific. They’ve got a lot of resources at their disposal, and it would be kind of a shame to not have Team Arrow lean on them a little bit to help solve this mystery.”

Which means that this week is not just a publicity stunt, but will also be a  major part of the ‘Arrow’ season arc in figuring out who killed Sara, which makes the whole cross-over even better in my opinion. Check out the trailer below and come back later this week for full recaps of both ‘The Flash’ and ‘Arrow’ the day after the episodes air!
