Y'all are saying this like "uhuuu I think maybe he'll free Dream at some point, I have absolutely no evidence that this will happen though" is enough justification to lock someone in prison lmao
Also, need I remind you that Sam was on Techno's side in the Schlatt revolution and didn't defend L'Manberg when it fell? Dude never cared about Techno's past stuff
All that aside, oh my god they were roommates!
