Seems like the skin degeneration on Wallace Klim is due to drug abuse. Will drugs create echoes?

Currently, I would say yes. That's what we've been anticipating. Again, it's a physical thing like anything else. That's the chemical addiction. With WiDoW, the staining of the nerves or the veins. I would assume that that stuff would transfer over because, again, it's a part of the physiology, like a scar. So I would probably say yes.

Or it could be that Wallace Klim has never been regenerated, not once, and that's just the long-term buildup on his original body. Who knows?

Or he's just super cautious.
