I love that unlike all of the previous regenerations fifteens first moments aren't shrouded in grief for his previous regeneration, instead I can start loving 15 right away as nothing was lost when meeting them. this doctors first action was breaking a cycle of grief and heartbreak not just for himself but the viewers as well and I love him so much for that. also no one stopped to pick up my poor little cringe-fail wet cat of a timelord up off the floor. how rude. however it was absolutely hilarious watching the toymaker brag about defeating the master as if the master hasn't died in practically every single appearance. like the toymaker isn't special for doing that.
