Research is well in Yori's line, but I'd like her to get out and explore at some point too. She'll take the sudden lack of flight a little personally. Lack of it will slow her down, but she's been practicing her city-running techniques.

She ought to be somewhat familiar with the oldest parts of the Grid and how Flynn originally set them up, which might help, though she won't be relying on her own memory if she can help it.

Therefore she's first looking at available sources, then searching for trouble spots. Help her get somewhere in either effort and she'll be glad of the assistance.
