Hi there. Welcome. A few pointers to get you started - AA will never really go away, you just learn how to handle it and realize it's not a big deal.
Secondly - you're having problem transitioning. Why is this? Because you are probably finding it weird to continue the conversation. You are going indirect - why? Because you are afraid to make your intent clear? This game runs on intent my man. But you will get to know that anyway. Just know that being indirect is alright as long as you are solid in your intent. So if your intent is to truly be indirect then you will be genuine and will have no problem with the conversation. You are stalling because you are being INCONGRUENT and you know it. You are using indirectness as a way to mask your intent. Don't do that.
A few key pointers here that will probably be useful:
Know what you want and go for that unapologetically. Stop caring about what she thinks. You are probably walking up to her and want to get to know her. Do just that. Get to know her. How do you get to know people? You talk about things. So talk about things, specifically about her. She will not find it awkward if your intent to get to know her is shown, either verbally or in the vibe or even physically (in the club). The important thing here is to own it and to stay congruent to that. Your midgame is not lacking it's just that you are setting up a frame from the beginning that you cannot hold - namely the frame that "I'm here to ask you just this one question about where the bus is." Once she's told you...great. Now what? Naturally this has come to an end. You have fulfilled your "intent" if that truly was your intent, but since it wasn't you haven't really, you've just been incongruent to it. Now you can go up to her with the same question and stay congruent to your intent. However you must be prepared to show it by continuing to talk and get to know her unapologetically or by stating it verbally - "Actually, I just thought you were really cute and I had to find an excuse to come talk to you." If you own it and do it FULLY it will work. Anything works if you do it FULLY.
So you see how it is not your midgame that is fucking up, but rather your framing from the beginning? The framing from the beginning is extremely important, since it sets the frame for the ENTIRE interaction hereon out all the way until sex and beyond. You want to, have to come from a man to woman frame, anything else won't fly. You are the man, she is the woman, and therefore you have to take action, you have to take the steps, since this is the ONLY way to get the girl. You have to risk it, but anything else will fail, be creepy, be awkward, etc. This is the ONLY way. An example of awkwardness would be you walking up to her and asking for the bus stop, then you are stuck in this frame and now changing to the man to woman frame is unexpected and it becomes this big moment where you have to suddenly state your intent. Your intent should be there from the start to avoid this stupid awkward moment. Get what I'm saying? If you use the example above of stating your intent right after, the intent should still be there in the opening bus stop line - you are asking her but you don't REALLY want to know

you are really here to...get to know her because she's cute. Now the conversation can fly if she hooks. How to up your chances of her hooking? Walk up and own it. Then get to know her, get the number or an instant date, and push for the most you can. If it comes to an end get her number, arrange a date and get outta there
Hope this was not too much information, but this just needs to get sorted early on so you're on the right track. Good luck bro!
