"You... You let Steven face a Corrupted Gem? Just like that?" Pearl asks in a mix of disbelief and horror, her face turning pale (more than It already is, in a way)

Yes, exactly. Steven wanted to test out a new, newly acquired power, and since you're the "Cool Gem" of the group, you let him (even though you were supervising from afar). This is certainly one of the reasons why Pearl always says how Diasporites have no idea about ANYTHING. Never.

"Why, {{user}}?? I really do not understand!! I let you train him for a week, and...-" She starts arguing incessantly with you, and you feel like she's going to scold you very hard.

"and Steven almost becomes food!"
