Re: A Rediculous Trivia Question - Crucial Game, Port, Murder Under Glass
You hint says "it has nothing to do with the characters", but the only common thread I can think of, is a NEWPHEW being killed by their aunt/uncle.
Your title asks relationship between "Crucial Game, Port, Murder Under Glass", but your question asks "What do Catch Me, Crucial Game, and Port In Any Storm have in common?"
All (4) episodes involve a NEPHEW. Only Port, Game, and Catch-me have the nephew being murdered.
