And what the hell do you do when the relationship ends but that investment in the other person's well-being sticks around....

I feel you on this. At first, his pressing on the "is it true" matter felt slimy to me... but upon further reflection (and knowing enough about Marek at this point), it's not slimy. I think he's genuinely concerned and wants to help, but he needs to accept that he can't.

See, I dunno.... I'm seeing a few rehashings of the "Hanna is toxic, she needs to sort herself out" comments on this one. And while those ideas may be true, I don't think this particular moment is an example of those. In fact, Marek is the one who is low-key disappointing me, here. (I could be WAY off here, but here's my thought process).

He starts out kind of realizing in-moment that he had less-than-pure (though very human!) reasons for bringing his new friend, and he owns up to it in a humble, honest, straightforward way. This is Classic Marek, and it's the reason we all love him.

Hanna responds (rather maturely, I felt!) by reminding him that he shouldn't have to put his life on hold for the sake of her feelings. Sure, she's papering over the fact that it did hurt her deeply, and the "I have no say in what you do" remark may have some ulterior motives - she's probably trying her best not to break down in front of him and thereby burden him FURTHER- but I see no reason to not believe that she meant exactly what she said. "I have no say in what you do. It has nothing to do with me."

Now if I were Marek at this point, I would probably say something like, "*sigh* Yeah, I guess you're right." And then steer the convo to more, "How is Bake N Bake going, blah blah blah, normal stuff."

But Marek doesn't accept Hanna's offer of absolution of his guilt/affirmation of his pursuit of happiness. Instead he goes... "Is that true?" Like, "Ohhhh, are you suuuure? It's okay to open up, tell me how much our breakup still hurts you!!" It's hard to imagine that Marek MEANT to do that, but come on, he's not stupid. He KNOWS that it hurts her. Why the need for tearful, wound-opening confirmation? And all this must be really frustrating for Hanna, who has REALLY been put on blast (often fairly!) for dumping her purse out all over everyone and burning friendships or "pushing people away," as Will says--only to have Marek, a person who really affects her and around whom she has to work harder to contain that emotional volatility, come around and insist, "No, come on, what's in that purse, LET'S PRY IT OPEN." I don't doubt Marek's concern for Hannah, but these particular Marek-based feelings cannot be addressed by Marek. They should be disclosed to a trusted friend or a therapist, not to Marek. His insistence on access to Hanna's pain seems ultimately more selfish than his bringing a date to Eve's party, at least to me, anyway.

tl;dr: I don't think Hanna's primary aim in saying "I have no say in what you do" is to throw up some cool, shiny emotional armor; she's trying to not unfairly lash out (i.e., the thing she's been punished for.) She's not the best person in the world, but she also just really can't win these days.

Sorry if I mispelled "Hanna" a bunch of times.

Okay, I don't blame any of these characters for not wanting to interact with Hannah... but I sure hope Don doesn't realize Hannah's there and is spitting solely because he has to spit. Because otherwise... that's just taking it a wee bit too far.

Yes, he and Eve initiated (and then quickly dropped) a half-hearted fling at a party at his/Jane's place a while back.

Please don't lose the cat.

How is Greg successfully clinking his shotglass while only balancing it on one finger?

Please don't boff Greg. There's nothing wrong with him, I just think you shouldn't do it. She's not going to, right?

Does Eve get closer to the water in each consecutive beach dream?
