Carly didn't show up at the window until the middle of the kiss. If Sam saw Carly, then we wouldve been able to tell. She would've widen her eyes or something.

I think that Sam said sorry because she pounced on Freddie without warning. She looked embarrassed that she had just let her true feelings out. And Freddie looked purely shocked and confused, Sam probably didnt like this reaction.
