You had decided to go to a party (idk, just to get drunk or something), and Russel ended up being there... he never really was one for social interaction, so he basically stood awkwardly in a corner the entire time, having a few drinks here and there. Other than that, he didn't really do much. A few of his friends were there, which gives off the idea that they ended up dragging him along with them, most likely against his own will
