A very nice episode! I could really tell that this episode actually didn't have any shipping... if you think about it long enough. What really happened was just Sam admitting it they kissed, and Freddie nearly dying (very funny!!).
Carly finds out. Freddie finds out Carly finds out Sam told her. Sam finds out Freddie found out Carly finds out. Sam finally finds out she was the one who told in the first place.
Did Freddie and Sam... like it? Since we haven't got to find out... we shouldn't assume anything!!
