User blog comment:Eobard95/The Flash Season 4 Ideas/@comment-27167599-20170323145920

 Interesting theory but I have   a another ideaI think that after Iris dies   they will save her by healing her injuries   not by changing the past. The Time loop World that   Barry created   to in prison’s Savitar    or something similar to it could also be used as a life support system   for Iris. Team flash will spend season four trying to figure out how to   Bring Iris   out of the speed   Force without killing her. Doing this would probably involve 22nd century medicine Which is how they first encounter Eobard Thawne.
