Gwen was headed to the dining car to see how her sourdough starter was. It probably died, honestly, because she hadn't been there to feed it. The smell of chocolate distracts her enough from her book where she's keen to find the source and when she pots Mr Stark with a spoon in her mouth and a tray of fresh brownies, she's kinda surprised.

"Is baking a hobby for you?" Because those brownies smell ridiculously good.
