The Flash Season 2: 9 Big Questions We're Asking After 'The Man Who Saved Central City'

9. Where Is Harrison Wells?

Last year gave us the mystery of just who is Harrison Wells, and after the shocking revelations of season 1 and his being Eobard Thawne/Reverse-Flash, the concern now is where is Harrison Wells? 

Barry is clearly shocked to be receiving a message from him beyond the grave, and it was another big twist when it turned out that his final gift to Barry was to finally take the blame for his mother's murder, and allow Henry Allen to walk free from prison. 

However, that isn't the last we're going to see of him, as Tom Cavanagh has (thankfully) been confirmed as a season regular again this year. Given he's believed to be dead, how exactly is that going to happen? Is just just going to be in a series of video messages and flashbacks, will he come back from the dead, or (and this is the most likely) is it another version of the character residing in an alternate dimension, who this world's Barry will end up coming into contact with?
