I caught it at the time, but I also watch the show with captions on because it's very easy to miss vital bits of dialogue. Esmail had this to say about the return of Leon.

That coda at the end of the episode was a delicious nugget not only do we find Trenton and Mobley, but Leon resurfaces, too.
We wanted to resolve all of the mysteries wed been setting up all season, Trenton and Mobley their whereabouts being one of them. We find out they have gotten away, or so they think. And here comes Leon, whos definitely an agent of the Dark Army. His intentions remain to be seen. Well definitely get into it in the third season.
