First date

You get up and walk over to were she is and start picking stuff up and giving it to her. "thanks" she says "it's really nice of you to do this" you hand her the last of the stuff and say "no problem. You know I hav'nt seen you around here before are you knew?" she smiles and says "ya I just transfers her. My names Marlene nice to meet you." " (your name here), nice to meet you to" you guys say by and go to your locker to get your stuff. The bell rings and the halls clear. Your almost in the class room when you see Marlene looking around in the hall confused. What do you do?
