Good for Liam to get some more catharsis, even if he isn't fully settled about his father. Liam is very lucky to have Marty as his pseudo-brother. One of the hardest things about being a child is not being able to see or understand what our parents are going through, and not really having a way to adequately communicate our more meta needs... I won't pass any sort of judgement on Liam's father, because there is too much unknown, really, but Liam does need to let more out and find that space for forgiveness because holding on to things the way he has affects him deeply. More and more, this is revealing things about how Liam ticks, and how that has affected him in both good and bad ways within his relationships (with Alek and otherwise). Seeing the contrast between Liam's relationship with his father and the more overbearing and involved family life of Alek shows why it hurt Liam so much - despite Alek's fears and issues with coming out, in a lot of ways he had something Liam wanted, an active relationship with parents. I feverishly doubt that Alek could ever have known how deeply that would hurt Liam, beyond just the act of being hidden away. Liam, at the same time, didn't understand how psychologically consumed Alek was by that fear... It was good to see Allie giving Liam some advice from the flipside of the coin; how broken is broken, indeed? Sometimes it takes some falls to learn how to fly.
