No, don't talk to them, approach them. Ok, the procedure.
1. get key from Pickle
2. talk to all
3. go upstairs and unlock your room, visit all others, maybe even click on her room door.
4. Go down and go very near to those guys, not click on them
5. Cut scene should come
As you interrupted this by going to the BF - could you repeat 2-5, please? And report?
