Spoiler! Spoiler! If you have not watched ALL of season 2 of The Flash! Spoiler! Spoiler!

So end of season 2 Barry Allen goes back in time saving his mother. Leaving us all like what the crap! & the people who have to wait until the next season comes out on Netflix because Hulu is no longer showing our favorite shows are screwed.

Now that leads both me and you here...

What If when Barry gets to this new 'world' the sacrifices he has to make are to great?
How will he get back to Earth 1 without his speed?
Will he want to go back after meeting this new worlds Caitlin?
If and When he returns home will 'his' Caitlin feel the same as the other Caitlin?

I do NOT own The Flash!
