Well, Dean asked them to bring it, and Daenerys intended to. She always does, after all. She notces the extra targets sitting around the archery range and makes a few mental notes that they're probably for her, considering Dean was worried she might destroy a few targets.

Well, this is a sort of time to show off, so...even though she does fear fire is destructive, even though it can cause fear...destruction isn't always a bad thing. Particularly in accuracy.

She takes her place in front of one of the targets, brushing some hair out of her face All three of her dragons are close by - she doesn't dare leave them alone anymore. Viserion is at her shoulder, and Drogon and Rhaegal circle overhead. Standing solid and strong and finally looking well-rested, Daenerys stares at the target as if she wants to figure out the best way to conquer it. Slowly, she takes a deep, calming breath in before she holds out her hands, sending a few fireballs out to torch the target. It's hard to tell where they hit, because it goes up in flames not long afterwards.
