I have been thinking about this prompt and my first thought was that Matt would be incredible nice to Foggy. Like: coffee with the perfect amount of sugar waiting for him in the office every day and Foggy wondering if Matt can actually tell the exact number of sugar crystals or something.

And then I thought something different:
The last time somebody left Matt was after he showed him how much he cared. All the people he cared about left. So...if he just pretends not to care it must work. Right?
