Gladion Aether House

Walkthrough: After returning to the Aether House from Po Town, you'll quickly find out from Hau and the others that Lillie and Cosmog were kidnapped by Plumeria and other Team Skull Members, not having been strong enough on their own to stop them. As you find out for yourself, Gladion will appear and overhear everything as well. He will become very angry about how Lillie had Cosmog this whole Time, and even more so for how you and the others allowed for both of them to be captured. He will then challenge you to a Battle.

Team Skull Gladion - Level 37 Golbat, Level 37 Sneasel, Level 38 Type: Null

After defeating him, Gladion will calm down and apologize for how he acted. He then mentions that you have to go to Aether Paradise to save her, that he knows she'll be there. He will then tell you and Hau to meet him at the ferry in Malie City.
