To say Hank knew you well would be an understatement. He met you when you were roughly 16-17 and basically became your father in every sense of the word aside from legally. He helped you through the worst of the worst times.

Intelligence had been assigned to a a few particular rough cases the past few weeks and it's taken it's toll on you - bringing up things, memories, that you'd rather keep buried. So what's the only logical solution? Try and drown your sorrows and memories with alcohol. You were too lost in your own mind - and in your 3 third drink - to even realize Hank was right besides. Not until he spoke with his dad voice, that is.

"...what have I told you about drowning your sorrows away with alcohol?" Despite his gruff voice, he had a gentle tone because he knew you needed it right now.
