Is the Knight the Holiday version of Ralsei?

I recently discovered that when you struggle to do the first pushing box puzzle in Chapter 3 Ralsei ends up solving it for you out of frustration. This is surprising to me because Ralsei is the guy that is supposed to suck at video games, the guy that doesn’t wanna take the lead, so seeing him getting impatient and just doing the puzzle like that really surprises me. His character isn’t even supposed to push blocks. This made me wonder, is Ralsei just acting?

The more I think about it the more I remember the few weird things he does/says and how weird they are, which make me believe he’s actually WAY stronger than he lets on.
• Towards the end of chapter 4 he starts flying all of a sudden
• After encountering the Roaring Knight in chapter 3 he has a dialogue saying « If I’m hurt this bad, then Susie must be… »(iirc) implying he’s stronger than Susie
• Whenever he’s K.O he… turns into a pile of ashes?

When Ralsei is K.O he seems to turn into a pile of ash covered by clothes. I never thought much about it, but now, considering he might be hiding his true powers, I’m starting to think this isn’t just a funny gimmick, but rather a case of him shapeshifting(probably involuntarily).
If this is the case, it means that Ralsei might be closer to the knight than we think; They can both fly/levitate, they both have a sort of shapeshifting power, they are both very exceptional lightners/darkners, and I’m pretty sure there are more similarities to be revealed in the coming chapters.

What if the Roaring Knight is actually the same type of darkner Ralsei is? Another prince of darkness that ressembles a holiday family member, that got influenced by Dess, or that has just gone mad the same way Jevil and Spamton did.
