I’ve seen a lot of people talk about how the 15th doctor crying every episode is cheesy, or annoying , or lessens the emotions the moment, but I have a different opinion.
I know rtd is sort of pretty much ignoring 14 and the bi-regeneration but remember why that happened in the first place?
The doctor was feeling to much and pushing it all down in the last four seasons AT LEAST, they’ve been through so much and 15 is supposed to be the best healthy version so 14 can heal. (At least that was my interpretation)
And crying in those situations 15 gets into is the most healthy reaction (except for when he immediately goes back to being “happy” so maybe he’s not perfect).
