The way they pulled it off makes Gohan smart for figuring out the plan from the first hit at least.I'm not buying that excuse. It's just a poor attempt at creating tension/friction between Frieza and Gohan.
Ah thats a shame. Yeah I like the premise of characters who dont usually interact teaming up like Vegeta/Roshi and Frieza/Gohan but the latter wasn't executed the way I wanted. I would've preferred some exposition of Frieza telling Gohan he would betray Frost.
