It's true. Even as Roland is talking, even as he's explaining why Inigo definitely shouldn't eat too much of the stuff, here Inigo is. Definitely eating too much of the stuff. He keeps eating it even as he's listening to Roland, like he's unable to stop now he's started.

In fact, the boy already seems to get a bit more jittery, considering the sheer amount of unadulterated sugar he's ingesting over here. The sugar high is truly inevitable.

"When does it start losing the yumminess?" Hah, look at this counterattack! Time to pull out some facts, Roland! Some cold hard evidence! Even Inigo's dear father can't keep him apart from this sugary goodness! "I've already had more than one of these now, and it's still yummy!"

(A true scientific experiment, clearly.)
