Silent but Deadly
Robin is silent almost all the time, never talking unless A. nesassary or B. she was talked to first. She is also very shy when it comes to large groups.
Robin, being the genuis she is, raided a police station at the start of the outbreak. So now she carries around a rifle, loads of ammo and wears full riot gear.
Robin used to be a collage student before this began, she also had a part time job as a waitress. With no cloes friends or family she had nothing tying her down from escape... except her kitten Doom, who normaly resides in her shoulder bag.
