Season two of The 4400 ended not with one, but two shockers. First, baby Isabelle turned into a 20-year-old overnight (now played by Megalyn Echikunwoke). Then, it was revealed that Jordan Collier (Billy Campbell), who was believed dead, is still alive. The third year begins with more surprises. While Isabelle was aging, so was her mother, Lily (Tippi Hedren, replacing Laura Allen), who fast-forwards several decades. Suffice to say, her husband, Richard (Mahershalalhashbaz Ali), is not pleased. Also, the Nova Group, a splinter organization within the 4400, has started to eliminate those they perceive as their enemies?including their own. 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 (Patrick Flueger), head of the 4400 Center, embarks on a relationship with Isabelle, while his uncle, NTAC agent Tom (Joel Gretsch), gets bad news about wife Alana (Karina Lombard) and good news about son Kyle (Chad Faust). Dennis Ryland (Peter Coyote), meanwhile, moves from the NTAC into the private sector where he continues to micro-manage the 4400.
