He lets Law infodump on him because he gets so animated
Corazon was there when Sanji first put the raid suit on, they were planning to use his Devil Fruit to sneak Sanji an and the others out before shit hit the fan.
Law going full nerd over Sanji in his germa suit is the greatest thing today. I bet on the inside he wanted to act like Luffy and Chopper when they saw the suit and wants to try it out, who wouldn’t when a character from their favorite comic comes to life 😂😂
~~Edit after watching a few more eps~
He found a couple more fanboys I’m assuming cuz they had tiny little blushes when they realized who that is 🤣 they didn’t Geek as hard as Law tho
