Love how the vest goes from punchline to lifeline without being heavy-handed about it. The Deborah scene hits perfectly, watching Doug shift from casual helper to someone who knows exactly what panic looks like and how to short-circuit it. I worked seasonl in Yosemite years back and saw so many people who looked over-prepared until someone needed help. That scar backstory tho, explains everything about why he's so attuned to people struggling.
