House would treat two gay patients like shit and get sued for being homophobic and cuddy would go "he's not homophobic, he treats everyone like that!" which does not hold up in court so instead he's like how can I be homophobic when I have a boyfriend? Wilson stand up. Everyone would turn to Wilson (who had ZERO warning about this) and he'd stutter before glaring at House and stand "yes, House is unfortunately my boyfriend"
Then they'd walk out of the courtroom and Wilson would chew him out which House ignores. Cue 3 days layer when Wilson says House needs to clear up they lied about being gay to get him off (ha) and they're not actually dating because he is NOT getting any dates like this. House would walk into the hospital cafeteria and yell "ATTENTION EVERYONE. Doctor Wilson is not my boyfriend." Wilson would nod for 2 seconds before House follows up with "because we're engaged!" and Wilson can't even be mad because why did he think for 2 seconds that House would make it easy for him
House would try to use this as an opportunity to demand less clinic hours (think of it as a wedding gift) which he does not get because Cuddy knows exactly what's going on and she thinks it's hilarious but she needs his ass working
Cuddy: yeah? You two are a thing? How big is he?
House: 5.3 inches
Wilson: how the FUCK do you know that
