I agree. I know it's been weeks, but Dora's moving right now and that's stressful enough; this isn't a good time for her to see Marten.
The whole thing about not being Marten's messenger girl is a pretty valid point, though.
I hardly think saying "hi" for someone counts as being a messenger. It's not like he's asking Faye to recite the freaking preamble* to Dora.
*that is, the preamble to the constitution, which I had to memorize and recite in 8th grade
In Faye's defense, it's reasonable for her to assume Marten might be interested in coming along because, after all, he finally psyched himself back into the coffee shop (and then reinstituted himself right into the defense of the social circle). Aside to Marten, though: I wouldn't recommend asking, by Morse or otherwise, if she's banging. Not your business anymore, friend, though she's free to tell you and might volunteer the information anyway.
Seems to me the social circle has moved past the breakup and a couple subsets of it are hinting to Marten he might want to head in that direction, too. Don't seem to be too many enablers in that bunch -- and that's not a bad thing at all.
Also, Hanners' little sly/shy Morse Code smile is cute.
