The only thing that makes me wonder this is........................ I gave a karma water bum like 5 bottles of Aqua Pura. I go do a mission and 2 days later he is dead. In his inventory he has 2 Aqua Puras. What if it killed him the fastest because he was already really weak? It kills the Mirelurks in the basin almost instantly. The Bos noob says it must be because they can't live in clean water, but what does he know? What does it mean when it says Auqa Pura has worn off some time later after you drink it? Is that the effects of the FEV wearing off until next time?
Rothchild seems like a BOS hardliner to me. Being head scribe, he could get that vile put in the purifier without Lyons knowing. Highly unlikely I know, but just what if?
