During my 2nd playthrough of SN2, I noticed something interesting in this scene in chapter 6 where ルヴァイド loses his helmet.
With ロッカ recruited, he tries to stop ルヴァイド but gets thwarted effortlessly. Afterwards, ギブソン strikes ルヴァイド with summon magic blowing his helmet off.
With リューグ recruited, he faces off against ルヴァイド and knocks the helmet off himself like a badass. Once again proving himself the cooler and better brother.
