Hiya Jo! My name is Jamie and I have four characters here, some of which could acquainted with Bree!
hardestofhearts is my UMCB doctor, Lalita Singh. She frequents the Dog Park to provide medical care, so if Bree sustained any injuries/needed anything more than general first aid, it's possible Lita could have seen her on one of the visits from the traveling doctors (which includes Dr. Peter Whelan/itakunai and their intern, Bea RodrÃguez/busybea_).
zeroes_and_ones is my Hellhound techie, Max Mendelson, and is probably the most likely to know/be friendly with Bree. He's really good friends with Cherry and if Cherry and Bree and friends, she'll know Max.
five_o is my police officer, Jane Rusten. It could be fun to explore something in regards to the pesky warrant Briar has out for her with Jane here! Even though that record probably was in effect before Jane came to the city, it could make for interesting interactions!
guard_duty is my recently introduced Head of Security at the LBJ, Luca Flores. Since there is an alliance between the Hellhounds and the LBJ, there is a certain amount of visiting between the two places so there is a good chance these two could have run into one another!
