Oh, I assumed he was talking about something written for him recently. Sulu showed up in Lower Decks not too long ago, and I know the franchise in general has a penchant for nostalgia at the moment. He certainly seemed to have a little more of a Takei tone in his LD appearance, but that may also just be him having grown more into himself over the years.

But yeah, if it's someone else playing it and it doesn't inform an established performance, then whatever.
