I did love the shocked look on Danny's face when Lindsay said she was his girlfriend.
Yeah, me too. It was like "Are you, really? Never thought of it this way" or "No... Not shallow and clingy at all..."
People are saying "Danny is a bastard, he lied to Lindsay." You know, even liking to see Danny and Rikki together (awesome chemistry there), I did thought "Poor Lindsay" when I watched the kitchen scene. It lasted until she made her "monologue of Doom". Then, I was wishing he had said on the phone "I can't have lunch with you because I'm planning on pulling a double with Rikki!" She so deserved to hear that!
I would understand her "monologue of Doom"
if she knew about Danny sleeping with Rikki because her perception of their relationship is that they're an item but,
as she doesn't, her reaction to him not reaching out for her is ridiculous and downright annoying. I cannot blame him for avoiding her and wanting to be with someone else. Jeez, Lindsay is a pain in the ass, of course he's avoiding her! And looks like since Ruben's death, besides the guilt and grief, Danny has been dealing with Ms. "You must lean on me even if I didn't do the same" and "You forgot the most important event on Earth, my birthday!". Patience has a limit.
When he thought she was still mad at him for forgetting her birthday, she talked to him like he was crazy, like her being all angry about that was a figment of his imagination, like he was hallucinating if he thought she would bitch about her birthday for so long.
And she must understand that her 'being in love with him' doesn't necessarily mean he reciprocates. Observing his reaction to her monologue, he didn't see them as a couple. Have they been sleeping together since SD? I'm sure they have, at least until Ruben died. Does it mean to him they are girlfriend and boyfriend? Obviously not. He was shocked to learn she saw them that way and was rooted to the spot when he realized she sees love where he sees sex.
Also, if she was really his best friend, as she claims to be, she would understand he needs space. As a lot of people pointed out, various characters reach out for Danny (Mac, Flack, Angell, ...) but none of them forced him to talk to them about it when he changed subject. He clearly didn't want to talk about it with them and they respected that. So, if he decided to talk about Ruben with Rikki, to whom he feels linked through his and her pain, I would expect Lindsay to understand and say "I'm here for you if you need to talk". But she didn't, resolving to shove her "pity me" show down his throat instead.
I was disgusted that she implied he didn't know that she knew what was to grieve and miss a friend. Of course he knew. He was there for her even if she wasn't talking. Now, if she was still grieving after ten years or so and she still didn't want to talk about it after all that time, why is Danny obligated to talk to her about what he's going through after some weeks?
I'm sure that she didn't want to talk about it right after the shooting of her friends happened (she couldn't bring herself to do so after ten years) so she should be able to understand him shutting everyone out. But she can't, obviously, because she suffers from the same illness that affects Mac: "Rules are for the others. They don't apply to me. I can be selfish, I can be bratty, my suffering is far more profound than yours and no way you can choose any person other than me to talk to."
Besides, in Danny's case, it's more than grief. It's guilt. People can say she felt guilt for not helping her friends but it's still different. In her case, she knows that she couldn't have done anything, that she would be dead if she had tried to save them instead of hiding. In Danny's case, he knows very well that he was responsible for Ruben and probably could have saved him, had he noticed earlier that the boy had been shot.
Now, we know clearly that Danny doesn't confide in Lindsay and her behavior annoys him (his face when she has her tantrums says it all). So, please, TPTB, don't make him magically discover he's in love with her too because he isn't. I might puke on my laptop and the repair won't be cheap.
