Tom Cavanagh will Return for 'The Flash' Season 3 as Series Regular
According to EW, it seems Tom Cavanagh will not be exiting The CW's The Flash despite how the second season concludes.
"Details on next season are being kept tightly under wraps, but I can tell you that Tom Cavanagh will be back as a series regular for season 3. Consider this: If the show does indeed move forward with Flashpoint, then the Reverse-Flash never killed Earth-1 Harrison Wells and his wife, meaning we could see the original Wells next season. Maybe. Hopefully".
This comes straight from EW's source. Fans will of course be awareof Harrison Wells' position, returning to Earth-2 at the end of the season. The news suggests we'll be seeing the timeline repaired, or perhaps spending a fair bit of time in the alternate universe in season 3.
