He decides to check out the Human town.

Big boy figures that 5 women and one Super mutant isn't enough loot for the slavers to stop their raids. He might be able to catch them if he leaves for the human town soon. Plus if they're not there maybe someone will know this symbol. Worst comes to worst it's a raid and just the idea of new captives makes his cock twitch.

Big boy and Biter head back to the tent and fill Evelyn in on everything. She agrees that Big boy is probably correct. If the raiders are still out there then Somerville Place, the name of the settlement apparently, would likely be the next target but he can't go out there yet. It's too dangerous to leave her alone here with no one but the cuck to protect her. Even if he leaves Biter behind one mutant wasn't enough to stop them before. He needs to stay at least until Block head recovers.
