13x07 Heroes

That was an interesting question about whether a cop is expected to be a hero 24/7, even while off duty.

"Have you looked at the oil lately?".
"-I've realized that sometimes I can be a bit of a dick.
- I'm sorry - sometimes or always?"

First, I'll confess to not doing my homework. I've only just begun to rewatch the series. But, the story of the off duty officer seems VERY familiar. I had to double check that I wasn't watching a rerun.
