"Oh no. Their criticism is VALID?!"
(A criticism that Catalina hasn't technically given about something she's not actually aware of, but still.)
I struggled with the phrasing and brevity of panel two because my natural inclination is to provide every possible detail, and there are a lot of details about why Diane and Lucy wound up doing that (see basically the entirety of The Legend of Diane).
What's important in panel two is what they can fairly be criticized for, however, not what was arguably sympathetic about their feelings and situation.
Specifically, it's what they feel self-conscious about. Putting in anything that could be seen as excusing it, even if it's not excusing it, would undermine it.
