[Although the reasons behind it aren't nearly as serious, someone else is here mainly to keep an eye on someone. Aidan knows what Helix is like around people. Even more so he knows what he's like when he's drinking and so the redhead took it upon himself to be the designated... omwati-sitter, just in case they're about to have a repeat of Thanksgiving or something equally annoying.
So he's hanging back, quietly nursing a beer and watching the game unfold from the side-lines. Of course, he doesn't have to keep an eye on Helix all the time since he's not Link and sooner or later he spots Saya. Naturally he'll make his way over!]
