Hey Daniel, answering your question: Matthew Perry, chandler's actor had serious drug issues, you can see in this season how thin he becomes, we don't know if allowing him to smoke was a way to help him get out of the heavier drugs, but from this season on he struggles on and off with it
The age difference between Frank and Alice isn't a problem for me, since Frank is confirmed to be 18 - however the fact that they had a student/teacher relationship makes it... let's say "problematic". At the end of the day, though - as long as everybody involved is a consenting adult, I'm okay with it... even if it is a bit weird.
who's hank? :D you mean frank :) i agree, i've always felt uncomfortable about their age difference, especially since he's only 18 (he was prob 17 when they got together). i love this episode anyway, it's just a show after all.
