there is a new years video where Christine catches him and Daniel making out at the pool
This was a skit they were doing.
Tom's straight. He has a girlfriend. You dig a bit deep into his Instagram you can find her. They've been together for quite a while now. I came across her account about a year ago so I'm not sure if they're still together...
And no, him and Elijah never dated. They were just good friends and if they showed any affection it was all part of an ongoing skit between him, Elijah and Christine (that Elijah and Christine were together but Elijah was cheating on her with Tom). He's better friends with Christine though I think because even after the whole split of Elijah and Christine, Tom still hung out with her. There's videos on both their channels I think.
How do I know all this? I've been a huge fan of all three of them and used to watch their videos all the time. They were hilarious back in the day. Tom still is.
