Tom gets out of a car, carrying baby Penny, who finally has some hair (up until now she's been eerily infant-like despite being almost two), and awkwardly tries to grab a bunch of groceries with his other hand but manages to drop a bag to the sidewalk. Gabby, who's jogging by (and looking very Barbie-licious in her pink track suit and pigtails), stops to help, and Tom hands Penny off to her. Gabby follows Tom inside as he juggles four packed bags along with a random plastic bag full of apples. Gabby: "Um Tom? I think she got sick." And, indeed, the front of her sweatshirt is covered in milky vomit. Tom laughs and turns it into a compliment: "Usually she only throws up on immediate family." Gabby: "I'm honored." The phone rings: it's Lynette, her boss loved her pitch, and she got off early! Also: she's by the grocery store, does Tom need anything? Tom is in the middle of telling her that he forgot to get bread when Gabby calls out that she needs a towel. A look of puzzled "what the...?" concentration crosses Lynette's face.
Cut to Lynette's car screeching to a halt in front of her house. Lynette sprints inside and greets a smiling Tom and Gabby, who are sitting around the table, mopping up Gabby's sweatshirt with paper towels. Tom asks Lynette if she got the bread, and she lies lamely that they were "out." Tom: "Of bread?" Lynette gives him a sort of "crazy, isn't it" look ["hey, our supermarket often runs out of our preferred brand -- it can happen!" -- Wing Chun], and then greets Gabby sunnily, saying how surprised she is to see her there. Gabby: "Well, I saw that Tom was overwhelmed, so I thought I'd give him a hand!" Which, while true, is maybe a little provocatively vague. ("I was jogging by just as Tom dropped some groceries so I helped him inside and now I'm cleaning your baby's 'compliment' bile off of my sweatshirt" would have been a little more sympathetic-sounding.) Gabby asks if there's a problem, and Lynette does a heinous job of pretending that there isn't. Gabby: "I sense that you're annoyed you found me here when you weren't home. Am I wrong?" Lynette is pointedly silent, and Tom finally clues in that something's going on, and asks what's up. Lynette, laughing her annoying "hahaha (not funny)" laugh, asks Gabby to explain, again, just what it is she's doing there? Gabby gets to her feet and yells, "If this has to do with that stupid little kiss the other night, I'm going to lose it!" Lynette tries to explain how the kiss combined with coming home to find Gabby alone with her husband might make a person think that Gabby is perhaps hitting on Tom. Gabby: "I have done nothing to deserve this kind of mistrust!" Lynette (prompting me to cringe hugely): "Well that's not entirely true...it's a small town. People talk." Tom, who's totally confused throughout this scene, asks again, "What's going on?" Gabby icily explains: "Your wife doesn't trust me around you because I had an affair with my teenage gardener." She gives Lynette a look of murder-death-kill and then zips up her sweatshirt menacingly. Oh, Lynette.
