Korrin just rolls her eyes at Thranduil and turns her attention back to the mission at hand. If he wants to bait the Seeker, that's his own business. She's right behind Cassandra, carefully moving along the rubble and more focused on safety than speed.

Morrigan's words get her to smirk a little, as she was looking forward to seeing her take the shape of whatever she pleased. Shapeshifting is awesome to see in action, so she'd never think to restrict her. The question has her arching an eyebrow, not exactly an expert on the topic herself. "That's all I've heard of it, personally. If there's more, then it'd be best to share that now."
