It is probably too early to really get into this discussion, but at some point, I am curious what people think of Joel's actions in the episode.
(I'm assuming this is a show spoiler thread. Sorry to those who haven't watching last night's episode)
There's a lot here because it comes down to which aspect you're talking about.
First, he's struggling. He knows Ellie is not his daughter but he's realizing he is turning into it. He's doing the things where he's trying to connect and messing up because he wants Ellie to see him as her dad. Ellie is processing her trauma and isn't giving what Joel is going for. All of it is relatable.
Second is the hospital. He's got the impossible choice. A cold, pragmatic Joel doesn't make that decision. For the good of humanity, he lets Ellie die. But he sees her as a daughter. No father is going to sacrifice his daughter, especially when he's already lost one. Marlene is right. He's not going to protect her forever. He should think of helping everyone else. But he can't. As a realist, Joel was wrong. As a dad, I couldn't do it.
Lastly, lying to Ellie. Everything I've said to this point has been about protecting her. Now he's protecting himself. Ellie believes she's going to help humanity but don't know she has to die to do it. Would she make that choice? Joel can't take that chance. He doesn't want her to know he just laid waste to everyone she trusted, especially Marlene. This probably was the most selfish part. Both he and Marlene knew they can't risk telling Ellie. Marlene said for the good of humanity, she'll make the choice for Ellie. Joel, in his grief, says Ellie might choose to die for him and Tess and everyone else she lost and he would lose another daughter by his actions.
I called this episode anticlimactic last night. I knew I had to wait to post that thought because I was right, processing it really is showing me the true depth of this episode.
It begs you to take a side. Joel made a choice early on and lost his daughter. Marlene made a choice and had to take the life of her best friend. Joel's loss robbed him of a chance and informed his decisions. Marlene's choice showed her emotions get in the way of what is right. And Ellie is caught in the middle.
