I think Lisa should leave the cafeteria before Jill and co. show up so that Aria can tell them she just needs time (and it's best if Lisa can meet up with her boyfriend too, but that doesn't have to be here), but I think Delanie spooking her off isn't the right way to go about it.
In the meantime, both A and F sound like good times to me.
