They'd had a couple of fairly easy cases (okay, the O'Brian case shouldn't have been so easy, but they'd had an unexpected amount of help) since returning from their vacation-- a vacation Devon and April had needed almost as much as Michael and Kitt.
Somewhere in the back of his mind, he was musing on Joana and David-- he thought they'd make good partners, in the end. Maybe not in a romantic sense, once they got the adrenaline-fueld attraction out of their systems, but good friends who could work well together.
Michael was thus all smiles as he headed into the lab-- maybe April would last through the summer after all, even if Kitt never did get around to showing her both his shapes. "So! What are we working on today?"
