Actual best friend Miles O'Brien, 3/3.

He just kills me in this episode, in the best possible way. He warns Julian as kindly as he can. He sees how Julian’s falling way too hard way too fast, but he’s not only worried about Julian. He’s worried about Sarina. This is not going to work out well. He knows it. So he lays it out for Julian. This is too fast. She is your patient. Woman of your dreams, eh? Okay. Good luck. And when Julian beats himself up with the exact same things Miles said to him, Miles doesn’t say “I told you so.” He says, “Yeah, I know. It sucks. You’re human. Come over for dinner. Keiko’s making tempura.”

Tie that to Ezri’s little comment earlier in the episode about how men pretend they don’t like each other because they can’t talk about their feelings, and I am just crey all over the place over these two.

Miles O'Brien = one hundred percent good dude. He's trying.
