Imagine the other compass is for Tubbo to Tommy...
Tubbo getting the compass then immediately darting to his home, after saying thank you of course to Ghostbur. He finds a blank book and writes a note for L'Manberg about his location and how Quackity is in charge until he returns since he is vp. He only takes a sword, a stack of potatoes, the compass and some dirt then immediately starts running to where the compass is pointing, desparate to apologise to Tommy without any of them being killed.
Tommy, knowing the compass points to L'Manberg and how he'll die if he goes, puts the compass in the ender chest - at least happy to know the direction of L'Manberg if he was to return one day. He continues his day like normal. The next morning, he awakes to Ghostbur being giddy about something but is told its another surprise.
Its the afternoon when his surprise arrives. He was sitting and listening to chirp in his tent when he was hugged from behind and a flurry of sorries was thrown his way.
A lot of tears was shed that day but a plan was formed so they'd never be apart again.
