Just want to pipe up and agree that Tumblr troll is trollish. Unfortunately, one of the ways to obtain Internet Fame these days is to successfully incite a blog riot, whether it's on Tumblr, or LiveJournal, or whatever. I've watched it happen a few times in the science fiction fan/writing community, and it's never pretty and makes the virtual lynch mob always look petty and stupid. Fortunately, it looks like this attempt has been an abject failure in that regard.
I also want to say one thing I really respect about the QC universe of characters. What is always apparent is that no matter what any particular character's issue may be, the rest of this particular group of friends has their back. Marigold felt confident enough to try this, and despite Marten's fumble, I'm sure as embarrassed as she is at the moment, she knows nobody is going to purposely try to hurt her feelings in this group. For anybody, when you're attempting to spread your wings just a little bit further, it really does help to have friends supporting you.
