Panel 1: Again, a callback to Emp’s sparkly-suit magic preserving her in a vacuum during her impromptu trip to the asteroid “Object 524” earlier in the volume.
Panel 4: Yeahp, Emp is talking to herself out of sheer anxiety, to the point that she’s even, technically, “wisecracking.” I’m not a big fan of the concept in general due to its tension-deflating tendencies, but here a little nervous joking on Emp’s part seems reasonably appropriate.
