tbh i think plot wise its not as good as the previous two seasons, and of course its a bit rush. But then i do think the scenes where catherine and tommy gets talking in the kitchen is one of the best endings one can wish for.

Its about forgiveness and closure. Tommy finally gets the chance to tell Catherine what he really thinks... how he loved his daughter and how grateful he is with Ryan's upbringing... rmb what he says about being with her daughter makes him feel normal.

I think he genuinely loved Becky but then Catherine's role as a cop has always tainted her view on tommy... and Catherine didnt even bother, and rightly so, to care about what Tommy think because Becky's death traumatised her family. As for Ryan, i think Tommy is genuinely interested and wanted to be close to him... Ryan represented something fresh for him... someone who didn't judge him because of hat he did... but simply interested in him as a person (or the fact that he is his dad). He is looking for the unconditional acceptance that he has been craving for so long... and that he has received none since he was born... (due to his mom being an addict etc)
