(2.) Happens during their summer break, they are working at a summer camp as councelors.
(3.) M/M are together (though they have a very "vinagar and water" relationship, but that always seemed to suit them the best) and I/A are together (a very sappy relationship).
(4.) Max is w/ Tess, at least in the beginning, they know that she is an alien, and Tess HATES Liz, but Max won't give up his friendship (at times it seems more :)) w/ Liz for anything or anyone (I guess in Tess's case it would be 'anything').
(5.) Liz starts dating one of the head councelors (you know the hot one that everyone wants to "get to know better").
(6.) Max is happy for her (or so he says), at least until he notices (first hand) that things between her and b/f are moving a lot quicker then Max likes.
(7.) Liz goes to Max for advice about having sex w/ b/f, she admits that she always thought and hoped that her first time would be w/ Max, which he admits to as well.
(8.) They start seeing each other (Liz breaks up w/ b/f) behind Tess's back. It is Liz's idea, she likes the idea of putting the *itch where she belongs, and tricking her at the same time, thinks it is a lovely payback.
(9.) M/M, I/A and M/L go skinny dipping (if you can find a way for all the couples to make love w/out it sounding like a porno video, go for it.)
(10.) M/L do it in the following places: in a walk in fridge, in some storage shed, in the woods, in his and her cabins, and anywhere else you can think of in a summer camp surrounding.
(11.) Tess has to catch them in one of these compromising situations. She slaps Max and tries to use her alien powers to hurt Liz but Max stops her somehow.
(12.) Max, Michael and Isabel have to decide between going home and staying w/ the ones they love, of course they choice to stay.
