Right, as I was watching it last night I was thinking - well, that was a nice hand-off!
Previously, when I would watch I would think, well, there doesn't seem to enough of a relationship between Buddy and his Dad, not throughout the whole thing - whereas the Romantic relationship really takes center stage, then probably father/son, and then "step-brothers" (But not as good as the actual Step-Brothers!)
But yeah, definitely IC is all Dad.
So Character Dynamics -
Resolve is super easy....
We already have Growth
We already have Approach
The last two are super easy given the Genre...
