I can't embed tweets but they have been tweeting stuff about each other indirectly. Not sure what it started with, but Collier said, "Really lol? You're making yourself look dumb...". This was after Harris posted all those pictures from his Ohio State visit. A few minutes later Harris tweeted, "Haha bro you were the back up plan!" and later tweeted, "Just because you went don't come back thinking your Tom Brady" . Collier retweeted a tweet saying that someone is still salty (mad, jealous) that they didn't get a E11 invite.
Maybe they aren't talking to each other but I get the feeling that they are. Gotta stick by our commit Collier though.
