I'm Liz and I have a few characters that would definitely know/have connections to Bree!
First up is Bode ‘Bishop’ Coldiron (minorpiece), the Hellhounds Chaplain and First Seven, so he’s been with the Hellhounds since their inception basically. Bishop is a ole’ Kentucky boy, born and raised in Harlan and spent much of his childhood and early adult years making moonshine (the family business) and mining coal. Out of the Hellhounds he’s usually the one with the most level-head, though recent events have thrown him for a loop. (His ex came back, and then his current girlfriend was marked as the rat, the officers went to jail, he got out and found out that current girlfriend was pregnant, she came back after being cleared of being the rat, then he became a father and the babies mama went missing along with his best friend shortly after.) Bishop has a history with Cherry, so it’s probably safe to say that he would know Bree, though I think she became a camp bitch after he was hooked up with Teagan, so it's unlikely they’ve done anything more than talk. :)
Next is my former camp bitch/jailbird Demi Rafferty (enavant) she’s a former ballerina who also grew up right in the thick of things in a motorcycle gang, so the Hellhounds are familiar to her and she’s extremely loyal to them. A lot of Demi’s hellhound related history happened before Bree showed up on the scene, but it’s likely she’s heard about her at least. Demi used to have an unofficial thing with the Dogs missing Dog King, Rodeo -- this relationship resulted in her being arrested and thrown into La Quinta. Demi eventually was freed by Isaac Callahan and found herself in a relationship with him, but events back in November found her being arrested for a second time and taking part in the jailbreak to get the Hellhound officers out. This means that Demi up until less than a month ago had been calling the Dog Park home (she now lives at the bar with Isaac), so it’s likely she and Bree crossed paths/or Bree has at least heard of her. It used to be that Cherry and Demi weren’t real friendly with each other, so if Bree is close to Cherry she might have had issues with Demi because of that (though Cherry and Demi are slowly working towards patching things up now that neither feel like they’re in competition with the other). That got wordy, but basically I’m open to any lines between these two.
The third character that Bree is likely to know is Sasha Whittaker (praelia) he’s the son of the Hellhounds Enforcer, Vic. He’s eighteen and often times is still very much treated his age around camp, although he is an tattoo artist apprentice to Noa Bellamy and that garners him a little bit more respect. Sasha valiantly attempts to flirt with the camp bitches, though I think because of his age many of them don't do more than flirt back and humor him pretty much. He’s a former MMA fighter in training as well, and a massive comic book nerd. He and Cherry are on good terms as well and if Bree knows Max at all then it’s likely safe to say they’ve interacted (Max is his adopted big brother.) Anyway, I’m open to anything with these two!
My fourth character is Nick Choi (stadion), He’s the LBJ’s head of resources and overall optimist. He’s been out to the park a few times and has also hooked up with Cherry on one occasion, so it’s highly likely Bree has heard about him if nothing else. He’s over all a very friendly guy, though he doesn’t agree with how the Hellhounds do things and probably isn’t their biggest fan. (He respects the alliance they have with them though and doesn’t judge people for the camp they’ve chosen.) again, if you've got any ideas for these two I’m definitely open to them!
Last but not least is Kitty Gilmore (duplicitat) who is pretty heavily Anti-Hellhound. She’s a young mother of two who up until recently had been staying at Fox Grove High school, but has since jumped ship to live at the Capitol. Currently her only connections to the Hellhounds are second hand connections through people like Pete, Nina and Bea. So it’s unlikely these two have crossed paths, but they may in the future. :)
