Molly lived in South Boston before the Great War, which she describes as a rough neighborhood. She saw military blockades, trigger-happy policemen and, looming over everything else, crime lord Eddie Winter. She much prefers pouring drinks for the Raiders in Appalachia to her past life.
When she arrived in Appalachia, she was one of three bartenders. Pretty Pete served alcohol and Lex served chems. However, both died early on, leaving Molly the only bartender. She now refuses to drink any kind of alcohol or take any chems.
From Russia With Lev - Dependent on one's behaviour towards her, Molly can be bribed with either 300 or 500 caps to reveal the snitch, since she overheard the conversation with Lev before he fled the Crater.
↑Vault Dweller: "Pouring drinks for bandits seems like a fast way to get yourself killed. You aren't worried for your own safety?" Molly: "Worried? Pfft. Hardly. Sure, I lock my cap stash up at night, but these folks are pussycats compared to the ones I grew up around.South Boston, before the bombs, real bad. Military blockades, trigger-happy cops, and looming over it all, the monster himself. Eddie. Winter. Nah, I'll pour drinks for these troublemakers any day of the week over that life again."
↑Vault Dweller: How'd you end up tending bar in Crater? Molly: Process of elimination. There were three of us in the inebriation business when we first set up - me, Pretty Pete, and Lex. Pete poured, Lex slung chems. But Appalachia ... seems it was just too much for them. Lex tragically OD'ed on her own stash not long after we arrived. Pete was so distraught, he got wasted and wandered right into one of those big batfissures. Now, I don't touch the stuff. My own little sacrifice. A reminder of the ones it took to get me my monopoly.
