Kate lifts her eyebrows back, but she's smiling a little as she does, then leans forward to taste the offered batter. It's not terrible, which is good, and she doesn't seem like she's about to choke on it and neither does Effy, which are also good signs. She has no idea why she's so invested in these stupid brownies, so insistent that they be made right, but she is. If they end up completely fucked up, she's going to be disappointed and not even completely understand why.

"I think they'll be okay," she says, shoulders rising in a brief shrug. "I mean, it tastes... like I think brownies are supposed to taste. Oh, shit," she adds, turning toward the oven. "I didn't preheat it. I don't even know how hot it's supposed to be. These are all things Marshall would just know to do."
