A new... look? Wrathion considers that, eyes flitting out toward the rest of the party goers.

"Then we have more than one thing in common."

Much more subtly, considering Wrathion has only lost the red eyes, but red eyes signify a lot for him. They shouldn't simply be able to take all that he is away! The thought is unnerving every time his mind touches against it, the idea that his very core being could be... suppressed? Ripped from him? Changed? Whatever it is that they've done.

"Our new friends must be... quite powerful."

If they can de-dragon a dragon, in Wrathion's opinion, that takes a lot of effort.
