After the... Incident last time, Vee was chucked in the brig as a disciplinary measure. Unfortunately, the rest of the crew forgot the brig was already occupied by a dangerous alien they had captured beforehand. Along with rearranging Vee's guts (again) it seems like it's also starting to override her DNA and turn HER into a slime creature too. It's a reversible process if dealt with early, enough but someone needs to come help her before it's too late!
