It makes him feel good, knowing that he's done all of this not because he wants show off or prove that he's awesome or whatever but because he wants to show her that she's worth it. It's not like it's a totally foreign feeling, doing things for someone else's benefit, but he's spent so long just bitching it out with Hermann in the lab and trying to win arguments and prove that his research is better that it's hard to say when the last time he'd gone so far to please someone was.

"Got a little Zitronengras-Hähnchen," he tells her, drifting over to the table so he can lift the lids off the plates and give a cheesy little bow. "Otherwise known as lemongrass chicken, with a side of mixed veggies for our enjoyment. Figured I should keep it light." He sets the lids aside and pulls her chair out for her with flourish, finding it really hard to keep the grin off his face because he's so pleased that this is going well. It's not like he'd imagined she'd show up and throw the table off the roof or anything, but it's the first time he's been able to do something nice for her since his cast came off, and he wants to make her feel as important as she is.
