episode 3x22 showed off some tech that hasn't been talked about in quite a while. Perhaps to remind the audience of this tech. [spoiler]What if H R used the holographic pen to make him look like Iris and allowed Savitar to kill him.[/spoiler]
shareNo, because we see HR talking to Cisco after Savitar already took Iris.
shareAgree, but Scorpwanna could be on the right track. HR's face changing tech looks like an obvious Chekhov's gun. So who did we not see in the last episode? Julian. And in his case taking Iris' place would kind of make sense, he has a lot of guilt for being Savitar's agent earlier in the season, and recently for his part in Caitlin's crossing over to the dark side.
Any other candidates? Immortals who would survive being skewered?
Jesse? Since they were on Earth 2. She heals quickly and they wouldn't tell Barry they made the switch.
shareYes, fast-healing speedster would do. Jesse's not on E2, but that's hardly an issue. Another possibility is that the switch took place while Savitar was busy ducking and running around avoiding speed gun shots. He dropped Iris and left her on the ground for about 10 seconds, more than enough to do the switch (especially if another speedster was involved). In this scenario, it could be anybody except Barry, Joe, Tracy, Cisco and Caitlin (we know where they are when all this happens). HR is a certainly a possibility, especially that every season we get a new Wells.
shareThat's definitely the popular theory.
[spoiler]I didn't think she died either because of the finale footage that leaked weeks ago.
Barry's reaction was genuine because he's not in on the plan.[/spoiler]
