Fiona's like, "And it didn't mean anything, because you knew it wasn't real?"
"No, that's the thing: I didn't know."
Lip heads over to Karen's to get her for another trip to see the robotics lab, and tosses stones at her window. Why didn't he knock? He thought she might have a boy up there. And as it happens, she did -- Jason Pierce helped her find a torrent site, presumably she blew him, and now he's gone -- and when Lip's face twists you have to wonder if he really has a problem with her choice, or the fact that this is still going on at all. Real or not real? Because as it turns out, Lip and Karen are playing the Fiona game with each other, refusing to trust even the idea of love in case they hit a double and everything goes to hell again.
Kev is still smarting for the 99 problems of Ethel that night, and can't even get it up for their eighteenth bout of sex today. "V, that girl needs us. I mean, you heard that messed-up story of hers. Not to mention she thought I wanted to have sex with her today." That one gives Veronica pause, but she's steadfast that the "freak" is not going to live with them forever, or even next week. Things do not end well, but you can see that Kev isn't giving this up without a fight. He grew up in foster care and it's clearly scarred him, but it seems like more of the fact that his Debbie part is coming out and he honestly can't handle the idea of losing this weird little girl to the storm.
Karen climbs into bed with Sheila, who is weeping, and they discuss whether or not Frank has abandoned them. Karen assures her that this little sojourn at the Gallagher home is only temporary, and things get way fucking dark: "Lip says he'll be back to normal as soon as he starts drinking again," she comforts her mother, and just like that the whole cast basically climbs aboard the fact that no matter how transient this Perfect Frank thing is, it needs to end immediately so they can all go back to their normal lives.
