I never saw that video before. Always good to see a new one from KA days.
As for their closeness, not surprising. The age gap between the two is large. He's an adult, while she's still the little kid Chloe we got to know at first. That could just as easily been a scene played out be a father or the cool uncle, yet in her case it's her brother, friend and mentor, Trevor. I don't think any of us can understand it fully because none of us have that. I've said it before. Without Trevor, none of us know Chloe through her films. Thumbs up to the ultimate ChloBro.
