Season 3 is the season of shirtless Carter so far, as we begin the episode with yet another excuse to show Colin Ferguson off. Carter steps into the shower, where he is assaulted by either freezing cold water from SARAH, who totally did that on purpose. He's out of body wash (they tried to make his body wash more masculine by giving the brand name "Grubby Guy," but it doesn't work), but not out of antiperspirant, which he takes out of his medicine cabinet in a gratuitous close-up even though we never see him actually apply it. Right, because I'm always taking my deodorant out of the medicine cabinet and placing it gently on the counter just to give me something to look at in the morning. SARAH continues to tease Carter, saying she's detecting high levels of adrenaline. Distracted by her nagging, Carter cuts himself shaving. SARAH offers him a band-aid, but Carter says he wants to look good for the wedding. "Good thing you're not the groom!" SARAH sing-songs. Man, how come robot houses have to be so snarky? Even the computer on Star Trek would get a good dig in every once in a while.

Carter makes his way to the kitchen, where Zoe's already having breakfast. Zoe makes fun of Carter for having a cut on his face, which is kind of weird in that I would never notice or care if my dad cut himself shaving. I certainly wouldn't announce like that. Then again, my dad was always careful and cautious when shaving, unlike Carter. Zoe isn't through with Carter, though. She insults Allison for working on the morning of her wedding and then criticizes Carter for saying yes when she asked him to walk her down the aisle. What? When did that happen? This wedding has come up so fast. I'm not ready! Zoe does have a point there, though: it's cruel of Allison to ask Carter to walk her down the aisle. Where's her dad? Her mom? Brother? Kevin, her son? None of them can do it? It has to be the guy who's in love with you? Poor form, Allison. Carter says he'd prefer not to discuss these matters with his daughter before spilling ketchup on his last clean uniform shirt. Wow, today sucks for Carter. But it can only go up from here, right?

Guess not, since Carter's sister Lex just showed up three days early. Zoe is thrilled. Carter is not. I'm cautiously optimistic. Lex immediately establishes herself as the "cool" aunt who travels all over the world to find herself as she shows off her two cats, who a Buddhist monk told her were Grandma Lil reincarnated. I'm not sure if Grandma Lil is in both cats or just one, and if so, which of the two she is. And would that make the other cat Grandpa Whoever? Honestly, I have a feeling she met that "Buddhist monk" at a the pet store he owns and he just told her the cat was grandma to get a sale. Lex further endears herself to Carter by calling him "monkey" and saying he looks like their father. Apparently, her New Age conference in Seattle ended early and Saturday is a good traveling day for Geminis, so she's early. I guess Geminis are not good with phones and calling ahead. Carter sends the cats to the guest room and beats a hasty retreat. With that, Lex invites herself to Allison's wedding, claiming that she "loves" weddings. What a weirdo.
