I'm not sure exactly how these two would see each other in the Studio. While his anger was pointed at Frieza, Bardock's a bit of a rebel and I don't see him being particularly nostalgic for being a soldier and towing the line. King Vegeta, while still using that title mostly to distinguish himself from his son, is not a king in the Studio and doesn't really hold any more power or influence than Bardock does. I had this idea for an exchange between them for this Dare, though.
