User blog comment:MakeShift/Arrow and The Flash to crossover in a two-hour event!/@comment-1104107-20140720023510/@comment-1104107-20140720132308

I'm not surprised to be honest that it is this early. Having followed alot of shows that have spin-offs, this is very common.

What I wonder is will this actually air on the same night as a true 2-hour event, or will the crossover story for both shows episode 8, be spread across two nights. It would be better if both shows air back-to-back, I may end up delaying watching the flash until the same night as Arrow, so I can see them both at the same time.
