So Sid didn't exactly hand the Sengoku Driver to Alfonso because he wanted him to be a wildcard. Alfonso - with the unexpected military background - just decided to beat up the obnoxious lot. God, I love this guy. At least stick around for a little while longer.
I could only catch a Youtube stream, which inexplicably skipped at least one fight. Gridon and Kurokage were turning on Baron one moment, and then a second later Jounouchi was lying on the ground. But seeing as the two look like the comedic Team Rocket duo, that unintended skip was probably symbolically appropriate.
By the way, you'd think Kaito would be busy foraging for more seeds at this point. I'd be doing that immediately the moment I get my arse kicked by Team Rocket.
