Grim’s contract
One thing that never sat right with me in the second half of the series is how Grim was a slave rather than an unwilling friend. In the first half of the series he could at least refuse to give in to their demands and occasionally put his foot down. In the second half however Mandy regularly forces him to do what they or rather she wants through threats of violence.
Let’s also not forget the fact that he’s constantly cleaning her house and forced to live in a literal dog house in one episode also the fact that Mandy *repeatedly* reminds him that she owns him despite the original deal being friendship.
This really gets highlighted in the Martian reaper episode and court episode funny as they were the major plot points in both is that Grim is property rather than a friend and should just take the abuse.
