The 4400's third season was widely considered its weakest, but solid ratings justified a fourth. The pace doesn't pick up until Jordan's return--in real life, Campbell took off 13 months to sail the world, but the concept and the characters remain intriguing. For instance, Shawn, head of the 4400 Center, embarks on a relationship with Isabelle, while his uncle, NTAC agent Tom, gets bad news about wife Alana and good news about son Kyle. Dennis Ryland, meanwhile, moves from the NTAC into the private sector where he continues to micro-manage the 4400.
