*Spoiler* - I'm not The Giant, so I'm just guessing, but I wouldn't be surprised if he was already thinking about the beats of this specific fight all the way back in Blood Runs in the Family. Not the panel-by-panel details, but something like "The Allosaur 'bite into a grapple' is kinda neat, what if the party needed a way to bring the dragon down to the ground? That would be awesome, but it'd look dumb if the dragon is way bigger, so I'll make them about the same size."
