Relations to Jack
Mark began to notice Jack by writing on Twitter to him "you have entertaining vidyas" according to Jack in a video. Mark then asked him to collaborate together for the first time for the game "The Forest."
They have since become good friends and have hung out at PAX Conventions together. When Jack and Mark revealed they had girlfriends, fans shipping 'Septiplier' lashed out at her and Signe for denying it. Because of fans constantly shipping them, through seeing fan fictions and fan art, it was presumed they had kept their friendship private because of it. Jack eventually came to their defense, saying he is only human and him and Mark will remain only friends.
After a year without videos involving the pair, fans became concerned, although it is now presumed they are back on track making videos together.
