Even if she could fly I would still keep an eye on her. Her not being able to fly just means that I'll have to watch out more. I haven't heard of birds that can never fly, even when they're adults, but they must be pretty good at surviving, otherwise they would probably die off a lot sooner. Since Archen are Pokémon though, they might evolve into a kind of Pokémon that can fly.

[He hopes that Archen will have calmed down by the time she can fly, if she ever does. Archen being able to fly and still acting like this could be disastrous.]
