Tom stops by on Earth to hangout with Star and Marco as the "ex-boyfriend but still friends" and sees them with a baby that oddly resembles Marco. The shocked expression and storyboard with his hand motioning is him wanting to converse with Marco privately if Marco smashed Star at some point, and if that's their baby. Marco tells him he's just overreacting and that it's his little brother/sister, but insists that Star and Marco babysitting shouldn't detract anything from Tom's visit. Episode goes on with all three of them and MJ going to various places, like the park, mall etc. with Star and Marco as doting babysitters and Tom watching how happy his friends are with each other and MJ. Tom knows he's a third wheel and is annoyed, but has to keep the facade of the cool "ex boyfriend but still friends".
All three of them then return to the Diaz house. Star and Marco are still playing with MJ with Tom sitting on a chair watching from across the room, trying to maintain his cool facade by putting some distance between him and his friends. Marco tells Tom to move closer to them, but he tells Marco he's fine where he is, Star then asks if Tom's okay, and he tells her that's he's fine, but on the inside is very annoyed of the situation he's in. After getting pestered by both of them to come play with MJ, he finally agrees to move closer, and gets up to move his chair and during the process sets it on fire on accident. Marco is freaking out and picks up MJ, Star is yelling at Tom that the chair is on fire, Tom is still trying to keep his cool facade and tells them that it's fine, the chair then fully combusts into flames. At this point Star has to intervene and casts an ice spell. That's why the storyboard has Star in clear distress while Tom looks at her confused. >>105849730
