He will pull through

Evelyn exits the tents wiping blood from her hands with a spoiled rag. She approaches Big boy and biter and tells him the good news. Block heads condition has stabilized and she believes he will pull through soon. With a Super Mutant's healing factor he should be up and ready for her FEV treatment with in one week but it's not all good news. She believes that the raiders who hit the camp are mostly likely slavers who take women and look to use them as breeding stock of their own or to sell them on the open market. She finishes by looking Big boy dead in the eye and says, "How do you think having a baby super mutant in their bellies s gonna effect their value?" The implication is clear. Big boy has to find these women and fast, or else loose all of the progress he has made since waking up in the vault.
