Hartley was pretty sure inviting his boss over to drink with him was a terrible idea. They may have been close once upon a time (admittedly not close enough to feel comfortable getting drunk together), but their relationship seriously suffered after the particle accelerator explosion and all those months Hartley spent distancing himself from everything Harrison and STAR Labs related. Even now, two years and a reluctant (on Hartley's part) reconciliation later, their relationship still wasn't quite what it used to be. So yes, this was probably a mistake. A mistake Hartley couldn't bring himself to give a crap about at the moment.

Hartley had already begun drinking when Harrison offered to let him be his problem, and he wasn't sure if it was the alcohol or his apathy that made him agree, but by the time he heard the knocking at his door any worries he may have had (about making a drunken fool of himself, about Harrison being judgemental and preachy, about getting too mouthy and finally losing his job...)  have mostly all faded away.  After all, the point to this was that he was someone else's problem for the night.

"Hello," Hartley said, eyeing Harrison warily for a moment before gesturing for him to come inside.
