FWIW: I still think sge is going to die

Will the timeline be changed ? Almost certainly not, since it would have major ramifications for Arrow as well, and those who only watch Arrow would wonder what tf has gone on.

(Which is pretty much what I felt at seeing a guy in the cell (Deathbolt) who had never even appeared on The Flash before).

I think at maximum, Barry will just get a chance to say goodbye, and then let/watch her die, because he knows the price to pay for letting her live would be far too great. (And I think his mom will tell him to let her go as well).

Nevertheless, looks VERY, VERY, VERY intense (esp from the extended trailer I posted).

I agree, but we are getting that spin off involving time travel.... so maybe he really will but the spin off will change it to what you said by the end of it.
