Default Something leaking

Drive home from work today (nice slow drive, nothing even remotely pushing anything), parked in the garage. As I got out of the car, I heard some sizzling. Kind of like water boiling. Look under the car and something is dripping in the passenger side exhaust just behind the catalytic converter. Does anyone have any clue as to what it might be? It appears to be clear liquid/water like in nature. Couldn't see anything from above when popping the hood? Possibly something with the HVAC system? Hopefully my video actually posts.

If you had the defroster going or the a/c, its the a/c hoses /lines sweating and dripping on the exhaust

Yea, it's the HVAC condensate drip tube dumping water. It is mounted directly above the passenger side exhaust pipe. We don't know why they do it that way, maybe intentional to boil off most of the water that comes out vs having people complain about puddles under the car. Who knows? Nothing to worry about though.

Yep, this, just A/C condensation dripping on the hot exhaust. Completely normal on every C7.
