It wasn't “I want you to look this up for me.” It wasn't “I want you to pass me the scalpel.” It wasn't “I want you to go down to the store and pick up some childlike food for my father.”
It was just “I want you.” In a way she'd never heard it from anyone else. She didn't know where it had come from, but guessed it must just be all the stress. He did look tired and... what the hell was she thinking? Why was she even thinking? A brilliant and beautiful man had just said he wanted her and all she could do was analyse. Typical Astrid, she heard her mother tut, always too busy working to have some fun.
At least five seconds had passed since Peter had declared some primal need for Astrid in a way that definitely wasn't fit for children and she still wasn't sure how to reply. Seize the moment! her inner voice was shouting. Think of the complications! her more rational inner voice was shouting. Kiss him! Was coming through loud and clear.
So that's what she did. She doubted it was a pretty kiss. Definitely wasn't movie-like. But it felt better than anything she'd done in a long, long time. It felt like a release, like something she'd been wanting to do, but hadn't realised until the very moment that she did it.
