He is warning her about ganondorf and telling her what he is up to, how he plans to take over Hyrule. After he tells Zelda and knows that Hyrule will take care of ganondorf, he leaves to Termina, resulting in Mm. But lets keep going and see what's happening at Hyrule. So, now everyone knows that ganondorf is evil. So, the sages try to kill ganondorf, so he can't take over Hyrule. However, ganondorf has the triforce of power. The sages can't kill him. So instead, they banish him into the twilight realm! And, as we all know, Tp says that ganondorf escaped the twilight realm. So basically, ganondorf was trapped in the twilight realm for over 100 years. This is why the world of Tp is a lot like Oot's, only bigger and much more evolved. It's 100 and something years later. The same areas are there, the same races, the same everything. So yes, ganondorf, after over 100 years, he broke out of the twilight realm to finally take over Hyrule, but this time, he's with zant. Now, they never say how zant got involved...but I'm guessing that while ganondorf was in the twilight realm, he met zant, and together, they broke out of the twilight realm to take over hyrule.
