So, basically I need some advice on a game plan I have for a friend. Here's a little backstory:
My friend is pretty decent with women but not aware of any PUA material. Recently, he met a HB10 at a party and by some divine miracle managed to hook up with her in the spa

I was so proud. To be fair she was a bit drunk but I could tell that she was still sober enough to know exactly what was going on. He is a year older than her (17, 18) and is tall, athletic and not bad looking. He's also a naturally nice guy which is probably his downfall. He's the type of guy who would spend an entire night looking after a girl he doesn't even know and not expect to get anything out of it. Which is great but the problem is that the idea of negs, disqualifiers and acting disinterested in the target simply doesn't click or make sense to him.
Anyway after he hooked up with this girl he got her number and began to text her, the problem is that he would always respond to her texts immediately and even sent her 5 texts when she didn't reply for a few days which I suspect DLV'd him quite a lot. According to him she began texting him less and less to the point where she was almost not texting him at all. Cue Party #2.
The next time he met her at a party she was already blind drunk by the time he got there. Apparently she was really nice to him the whole night but since she was close to vomiting he ended up babysitting her the entire night. After she had passed through the worst of it they pretty much just spooned (she told him to "Hold her") and then they fell asleep.
The next day he got a text from her thanking him for looking after her, he replied with the usual "No worries, all is good" and hasn't gotten a response back yet. I feel bad because she's the first girl in years that he actually wants to pursue (out of a one night stand).
Ok I know that was really long but I tried to make it as short as I could. Anyway another one of these parties is coming up and both of them are going to be there. I have a basic idea of what needs to be done both by him and by me as a wingman but I'd appreciate any advice you guys could give me. The more detailed the better.
Thanks,
