Alex's clothes seem to be part of him, since he shapeshifts it back on.
Wonder what would have happened if he woke up wearing something dumber... Well, it was already weird that they were dissecting a guy without taking off his clothes.
Programming clothing damage is a bitch (or so I am told). Or clothing moving at all. It's like how every character with a hood or hat will NEVER have it fall off even if you toss them in an aviation wind tunnel and demand they do cartwheels.
And I doubt anyone wants to play a shoplifting mini-game whenever Alex needs clothes.
If dead people smell anything like dead animals, Alex must smell awful.
Unless he has some VIRUS AIR FRESHENER ability we haven't been told about.
And Alex is never shown sleeping. Does he even need to sleep? Since he's not really human, and all that jazz.
Though I guess he doesn't pee or poo since he just keeps gaining biomass. So he doesn't sweat either?
I assume Dana has running water... or her safehouse smells terrible or she's risking zombie hordes throwing her business out the window like it's 1830.
