Panel 1: ANOTHER unnecessary prompt. You've met Gerald before, you know, Liz. This may be an off-and-on relationship, but it's not a brand-new development.
Panel 2: Liz, shut up! Even though I don't believe Elly meant it when she said April and the Continental have "just an innocent crush", you could have steered her further in that direction and saved April from the chastity belt you KNOW Elly's having made for her while she's away! Don't incite her with this talk of "passionate, all-consuming adult love"!
Panel 3: Elly really looks like she wishes Liz would shut up too.
Panel 4: Oh brother. I feel a flashback coming on. I'll have to check, but I think this might be the same guy we heard about years ago: the paperboy for whom Elly dyed her hair red with food coloring, who alternately ignored and used her as she followed him around.
ETA: No, that guy's name was Colin Winch. Still, it wouldn't surprise me to get a reworking of the same story with a different name.
