Kevin and Kerry von Erich interview - USWA/WCCW 1990

An interesting interview Marc Lowrance conducted with the von Erich brothers around Christmas of 1989. This is from the former World Class, a post-merger USWA. It's interesting because storyline-wise, it seems like the two brothers are very much headed in the direction of a match (or even a feud?)*. I know there's stuff on YouTube with Kerry as a heel, did Kevin ever turn? The vibe is kind of off with the two brothers, so I'm wondering where the booking was headed. Does anyone know what eventually happened? *Or that could just be me with wrestling brain thinking that if they lean hard in one direction, they're definitely going in the opposite direction.
