Such great character growth for Pete! In the beginning he was always chasing what he didn’t have, trying to be like Don, and feeling like he had something to prove.
But, now he’s realized what’s important. He doesn’t want quick office flings, illegitimate children, and the pitch to beat Don’s. He wants to do right by himself, his love, and daughter.
It was so full-circle. They started together and ended together, but in between Pete figured out who he wants to be and got to a much more settled and happy place.
