Cassidy actually being home isn't always common, but somehow Diego always manages to time it just right.

The knock isn't something he really recognises as Diego's, high and clueless as he was last and this time, but it's vaguely familiar as the good ol' cop knock. When Cassidy answers the door he doesn't seem all that concerned by the chances of a cop though, swinging it open with a half-smoked joint dangling from his lips, and eyebrow arched.

"Yeah?-- Oh, it's you." Sorry not sorry if he doesn't sound too excited about it.
