Would have posted more about this season but been preoccupied with my own regeneration cycle as it were.
Anyway, this season so far is still recovering from last season.
Nora needs to go back to the future, but she will likely be around for the impending Elseworlds crossover, which since the Monitor is said to be in it, we may as well call it the Crisis crossover. Also John Wesley Shipp will be in it as the 90's TV Barry Allen, thus I predict that they will pull a hat trick as it were and it will be the 90's Barry Allen that disappears forever in the Crisis.
Barry having the Flash Ring is nice, even though he shouldn't have it yet as it and the suit are not invented until the new Atom comes along.
Though I would think Cisco could study the ring and suit and replicate them....
Also Nora being in the present shows that once again they are playing fast and loose with time travel and paradoxes and apparently do not care. RF still exists despite his linear ancestor killing himself in Season 1. However since Barry exists as the Flash and his origin and RF's origins are hopelessly intertwined it is likely that it is Barry's existence that sustains RF in the time stream.
Killer Frost, glad she is back and while she is Caitlyn's bad girl persona she doesn't seem to be evil/insane now. We'll see how long that lasts.
Episode 100 is also supposed to be the return of Barry's enemies like RF, Zoom and Savitar...ugh....
overall I am really hoping this is the last season of Flash and Arrow.
Good to see you here IM Unit 07. I know you've been busy on the GL board . . .
