 When the character of Donut is introduced, Grif is arguing with  Simmons over a time when Simmons refused to go to ?Vegas Quadrant?,  and fled in an escape pod. This references a situation the Red Vs  Blue team experienced once before the series was made. As half the  group of friends were from Austin, Texas, and the other half were in  Los Angeles, California, some would occasionally travel to visit the  others. One time, when most of the Austin group visited the LA  group, they decided to go to Las Vegas, as the Austin group rarely  got the chance. All was going fine until Gustavo Sorola,  intoxicated, refused to go to Vegas with the rest of the team. He  opened the door to the van they were in, running all the way back to  the hotel they were staying at. There, he left a note saying, "See  you in Austin, Gus" and was found the next morning still in LA.
