Hm, when Sans says "Our reports show massive anomaly etc." during his fight, I am pretty sure he's thinking about him and Alphys. Since they researched determination, they most likely came to conclusion that it is the cause of timeline resets. It would make sense if Alphys asked Sans to help hunt down the thing she messed up...
