I know this post was originally commenting on Dirk and Todd’s relationship but I wanna also ramble a little about Dirk and Farah’s relationship bc honestly I love them, that’s just how their friendship works.
Farah isn’t a very touchy/huggy person and Dirk knows this and respects it. We see it in S1 too when Farah is emotional at Patrick Spring’s house and Dirk doesn’t really know what to do so he pats her shoulder. I think that was the beginning of a really wonderful friendship for them, in that moment they both realized they didn’t know how to comfort or be comforted and they found a likeness in that awkwardness. So while Dirk can convey his love and his appreciation for a person in a hug, he conveys the same thing to Farah with a less touchy gesture bc he knows she doesn’t particularly like to be touched. So they do shoulder bumps, shoulder pats, little pokes, high fives, and other gestures that seem less intimate but for them it’s the same as a hug.
