I actually really like the top strip. It's a solid Roz strip, and it provides a buttload of exposition in a way that I thought felt natural.
However, Chloe's naked skepticism kind of kicked the legs out from under the suspense of "dorothy or roz for RA," for what value of suspense there is. And so I was sad and I shelved it. I tried it out a second way with Dorothy added instead, but that strip wasn't really working either, and I moved the parts that did work ("see ya round!") into its own strip that culminated way better: http://www.dumbingofage.com/2017/comic/book-7/02-everything-youve-ever-wanted/labpartners/
The exposition that the single strip delivered was eventually split up piecemeal to other strips. Part of it here: http://www.dumbingofage.com/2017/comic/book-7/02-everything-youve-ever-wanted/volatile/ And the rest of it in the strips that just ran these past few days.
