Somewhere in there, Lexa is hurt by a rock knocking against her arm and scraping downward. She doesn't realize until she's back up on the main level and ready to move, when some of the air kicks up dirt into the wound, bringing more awareness to it. As someone with already present pain tolerance (she's fought a lot in her life—she has to have some resistance built up already), it's odd to have almost no recognition of that now.

She's caught up in glancing down at her arm, at the torn suit, but then begins to move, chasing after Clara. If nothing else, the two of them should be able to act with whatever Cayde has in mind.

The problem is that Lexa keeps an eye on Cayde and remembers his great act of brilliance from before.

Yes, she decides that it's time to come up with a backup plan of her own. ... While she's moving, that is.
