Victor Tanzig Seasons 5-6 Cliffhanger/Spoilers 

Thomas fell into a very bad coma

If Thomas doesn’t return, then it would contradict Wilbert not bringing dead characters into his railway series books. So I believe he has to return, Victor even said that he’s going to bring him back

Thomas could return in The Oil-Crisis Of Sodor

This is my least favourite one of these videos. The long silences and editing is bad
