Derek had expected the reaction Jackson gave him. The sudden spike in his heartbeat, the obvious reflexive jolt of surprise - it was something he had seen too many times to not be able to predict. A part of him found it amusing even that Jackson had let his guard down enough to be startled in the way he had. Though, he supposed he hadn't made the kind of enemies Derek had to learn to expect danger in your own home.

The sudden anger, no doubt an attempt to cover his earlier surprise, was just as expected. He'd never placed any faith in the idea that Jackson might change, learn to react to the word with more than anger. He was glad he didn't, the last thing he wanted or needed was to disappointment himself more than he already had.

"Are you really that surprised to see me?" He wondered, arching a brow as he continued to watch the younger male. His eyes never left Jackson's face and beyond the small quirk of one corner of his lips, he did a good of keeping his amusement with Jackson's reaction to himself.
