{125}{}{In fact, you could help me perform the field testing. Interested?}
{126}{}{Field testing? What do you mean?}
{127}{}{Not a chance.}
{128}{}{I've prepared a small sample of the serum but it needs to be injected into a host.}
{129}{}{I'm not letting you stick any needles in me!}
{130}{}{That's it, I'm out of here.}
{131}{}{You? Oh, no - the serum's not refined enough to handle such a low mutagenic quotient. It must be used on a super-mutant. Inject the serum into a super-mutant and then come back and report the results. I understand Broken Hills is full of them.
{134}{}{Well, it should cause a regression in the genetic matrix that results in the destabilization and assimilation of abberant DNA, leaving the host free of mutagenic potential. If I knew for sure, I wouldn't need you to test it.}

Kill dialogue
{147}{}{And... How did it work?}
{148}{}{It killed him! You said it would cure mutants!}
{149}{}{He's dead, Jim.}
{150}{}{You misunderstood. I said it would remove their mutagenic potential. The process does seem violent on the system, though. Oh well, more refining to do.}
