Zoom and Savitar both have a tendency of saying things they mean literally, giving hints to the audience/team Flash knowing they will be taken a different way. It's a testament to the writers that IF you are paying attention you can see what these same statements really mean in the long-term. But also When Barry came out of the speed-force a couple episodes ago Tom Cavanagh did his absolute best acting without saying a word. At Barry's house the expression, the emotion, the nervousness and vulnerability on Well's face rang of HR Wells. A man that hadn't even been conceived of yet. And if there is one thing season 1 Wells, the imposter who actually did care about the team no matter what else he was, and Earth-2 have in common it's that on the rare occasion Joe West and Harrison Wells are on the same page, you would do well to listen. Before the team figured out that Harrison Wells was the man in the yellow suit one of a VERY few things the pair agreed on was that if Barry faced RF in such an emotional state he wouldn't stand a chance. Here Harry and Joe are a united front on that same point.
Also, the man in the Iron Mask does not fade of into the sunset. He is always on call throughout season 3 and 4. John Wesley Shipp's character of Henry Allen dies in the first few seconds of this episode. Enter the actual Earth-3 speedster Jay Garrick. Who will proudly stand guard for as long as team Flash needs him. And of course Barry saves his mom...which finally teaches him the consequences and the dangers of 'fixing' the timeline.
