Well, that was disheartening. Her teammate really was a retard. Why, oh why couldn't she be stuck with the cripple again? Vriska simply shook her head in the most condescending manner she could muster before returning to her work - too many irons in the fire to respond for now. For a few wonderful moments, there was silence. It was blissful, in a sense - it meant that she had time to go back to her work. This was important stuff, after all - without her horns, she just wouldn't feel right. And besides, loathe as she was to admit it, it wasn't like she had anything else to do at the moment. Reconnoitering and reconnaissance were two things she was not in the mood for. However, cutting things and looking at least slightly appropriate for someone of her blood - someone of her race, really - were two things that she felt far more positively about.
With a few more cuts, Vriska managed to get out a second properly sized block. There - now to figure out some way to trim it down. The former troll grabbed both blocks with one hand before finally turning to face Vanitas. After all, she'd had time to express her disbelief at just how stupid he was - she could afford to dignify the other with a response now. (She sincerely hoped he'd understood the meaning behind her silence. It would have been a shame, to have such flawless sarcasm wasted on him.)
"That's a complete load of musclebeast-shit and you know it." And now, the coup de grace - a supremely confident smirk, intended to convey just how stupid what he'd said had been in case he'd somehow missed it. She was quite certain he'd missed it, actually. Wasn't it thoughtful of her to elaborate so nicely like this? "And it has nothing to do with my heart! Wow, that'd be even dumber than your question."
