He was believed dead after the particle accelerator disaster in Season 1, then actually died in the Season 2 premiere, then died again shortly after his introduction on Earth-2.
It could be intriguing to see how Team Flash would react to yet another death of Ronnie Raymond.
Caitlin barely even mourned him after his first death.
Personally, I’m hoping for a version of Ronnie from another Earth for one simple reason: he dies a lot, and I don’t think the show will be able to escape the fact that Ronnie Raymond dying has become kind of a running joke.
