It really kind of sucked to be Tom, didn't it?
Murph is obviously daddy's little favorite, and then adult Tom kind of gets character assassinated as this bitter *******, and then never gets to see his dad come back, even though he was the one sending all the messages all those years.
Also, I guess we can assume he died by the end? When Coop comes to see Murph, did he ever even ask about Tom? lol.
