So on the way to Graveyard Planet, Artemis will clean up the BL4 lab. In the process he'll try to isolate some of the virus that is very likely still in the lab--perhaps in the blast radius? He'll suit up and everything before hand of course (virologists always keep spare hazmat suits!) and make sure that the integrity of his lab is not compromised. He has an immortalized Arhan cell line--his own, actually-- and so he'll try to culture the virions in a flask of cells until he has a concentrated enough quantity to do work on. He'll be keeping control disease up while doing this...just in case.
