Nothing in this episode contradicts there
Except for the whole going out and conquering someone as opposed to defending sovereign territory. There's a pretty huge gap there.
Her healing abilities previously fought off an infection. Not shrapnel. There's nothing inconsistent there.
Joe: Hey Steve, working on the new healing abilities for our genomes?
Steve: Yeah. It will be great to fight off any foreign agents.
Joe: Yeah, the flu can be a bitch to get through.
Steve: So can spears.
Joe: Wait, spears?
Steve: Yeah, they are a foreign object entering the body. Why even now, your body will work to counteract having a spear in your shoulder. It will start once the clotting happens and then heal itself as it was designed to do in the first place.
Joe: Yeah, but then I'll have a spear in my shoulder for the rest of my life.
Steve: Unless you pull it out.
Joe: Oh you mean if it doesn't do too much damage on entry, you could just pull it out?
Steve: Yeah. You need to use at least approximately the same angle but if you are OK with it going in, you'll be fine with it coming out.
Joe: So you can't regrow a major organ but you can repair something damaged?
Steve: Heck yeah. Come to think of it, we have transporter technology so we can beam out the foreign object if necessary and large enough.
Joe: But what If I don't want the flu but am OK with having a spear in my shoulder? Can you program my genetic structure accordingly?
Steve, I suppose so, but we're primarily enhancing and accelerating something your body already does naturally. We could make a spear exception but that would be more work and be stupid. Plus anti-spear.
Joe: Wow, thanks for the help!
