I guess somebody named “Tabitha” led the bunch that freed him. “Do you know how he got away from the NCR?' Turned out some of them 'Night Kids” - whatever you call those sneaky Super Mutant types - got in and busted him out.I tried to buy him, just so they’d stop hurting him, but they didn’t want any of it. Boy, they sure treated him mean down there. Eventually got caught somewhere around the Hub, back in NCR. Wandered about after that 'Master” fellow died. Far as I can tell, he’s one of them original Super Mutants, what came from the Boneyard. I know the name sounds bad, but he likes it. “Do you know anything about that Super mutant walking around town?' Oh, heh.“Do you have trouble speaking?” Mmm-hm.“Nice to meet you… Mahsohfabish.” Ba peasure is ah mah.“What’s a Super Mutant like you doing in a place like this?” Ha ha ha! I wash ma bown.He found Westside and just sort of… stuck around, doing odd jobs and protecting the town from Fiends and raiders. They refused to sell him, but when Tabitha’s gang eventually freed him, he didn’t forget what Klamath Bob had tried to do for him. He was a slave and endured torture (including having his tongue cut out.) Klamath Bob, one of the town’s merchants, tried to buy him to relieve the poor guy. In Westside, you can meet a friendly super mutant with a misleading name Mean Son of a bitch.
