Today we learned, Big boob is quite open in her relationship, she still hates Stu-boy probably because she is sexist since we also learned that...
Stu-boy is gay, and he will kill himself for his friend, he also has low self esteem, and problems to start over.
Also that the airport lady with the manly voice didn't know bout those 2 being dead, or she is racist, which in the end is hard to prove, since well... Stu-boy did blow himself up, using his bombs which were real, which he carried to the airport, clearly an act of terrorism.
