Tommy being all upset about Ranboo and Tubbo being married now (his worst anxieties that everyone is going to leave him and find someone better), and pouting about it on the couch while babysitting Michael (they have a CHILD together, they're going out on DATE NIGHTS, they're ABANDONING him!).
Only for them to come home and Ranboo beelines for Tommy and kisses him on the cheek. Tubbo snorts at Tommy's face, how shocked and confused he looks. Tubbo joins on Tommy's other side and firmly plants himself in his lap, holding up a ring that looks a lot like their wedding rings.
"We agreed we're gonna marry you," Tubbo says. Ranboo splutters a bit about how Tubbo was not supposed to be so blunt, but also nods enthusiastically.
"I don't get a choice??" Tommy doesn't want a choice. He doesn't trust this, because this promises him all he wants, not to be abandoned and left behind. It's too good.
"Nope. You're stuck with us now, bossman."
(It turns out their 'date night' was just them planning to propose to Tommy, and having Tommy babysit Michael ensured he was already at the mansion.)
