I don't know if they'll be able to incorporate Jay, but I'd like to see:
- Less mulling over on Barry's dead mom and imprisoned father and more Barry Allen becoming the idealistic and optimistic hero, The Flash.
- Building up the Rogues, especially Captain Cold.
- A fight with the Turtle, maybe?
- Focusing on the start of Barry's relationship with Iris.
- A Wally appearance (and maybe a cameo or nod to Wallace).
- I guess we'll probably see August too.
- Nods or allusions to the Reverse-Flash.
