I thought not letting Wally be fun without hubris and consequence was mistake initially, but it's part of his growing arc and Barry pulls this crap all the time every season, but under the "right personality?" I don't know. We're seeing Wally not as some nice kid uncle Barry can mentor from being wayward. We're seeing Barry meet Wally as he was in his Mike Baron run. That Wally eventually grows out of it with the help of Linda, Hartley, Iris, Jay and Max, and writer's like Messner-Loabs, Waid and Johns, whereas Barry's dead and honestly had Barry seen him like he was in Baron's run he'd have been disappointed if how his behavior during Wolvman's Titan's is any indication, they were drifting apart by the Trial.
Iris having kneejerk self doubts is to me reasonable because in the end all she wanted to do was be with Barry and talk it out like couples should, but it is Barry this time that's making it difficult by cutting her out once again, which I take one, or two episodes tops for that status quo to be over because writer's are predictable and can't let well enough alone when it comes to stability. I think they have to be together for her death, or else it becomes another case of Laurel where it's a what could have been squandered. Barry needs a different reason to react to a girl's death than Ollie, or Matt Murdock (in comics his ex's die a lot more than his current girlfriends so). More like Gwen Stacy unfortunately, if we're going with Flash as Spiderman theme. Fail by your hubris, great power, great irresponsibility theme.
Personally I'd rather they keep the West siblings alive and not turn Wally evil and actually continue developing them as characters instead of double downing on their mistakes from previous seasons like they do with Barry where we're bound to always have another "The speedforce is angry episode" now. That's just me.
