ever since they talked about sanctuary moon skulduggery's wanted to watch some, so maybe mb has shown him a few episodes???

they probably have spent time in the library together, just doing their own things in each other's presence too

going forward after the island i can definitely see skulduggery trying to aim for more interactions that are quiet and relatively free of questions too. mb got him feeling a certain way about how he handles friendships and he wants to do better, ok :(
