This was a good opener for the Crossover. The great thing about it is they didn't rush into the crossover like they did last year, this time they were able to slowly start it up, and the invasion began in the last ten minutes of the episode. Sara & Alex hooking up was something that was going to happen. the moment Alex was announced to being in all four episodes. I like the fact that this has also started the story to help Alex move on from Maggie.

The woman talking to Barry was most likely either is future daughter or grand-daughter. I think it might be his grand-daughter because she seemed to be in awe of him, and it sounds like she might not have met him. I expect she will make more apperances down the line, while I doubt she will be in any of the other crossovers, I think she will appear in the Flash.
