I knew tonight's episode had to be in two parts. Would that they'd been aired back to back. We have to wait another week for the confrontation to escalate between the 4400 who are well and "ntac" (tsk, tsk).This program is full of surprises. Keep up the good work USA, this series is a definite winner. When The 4400 characters regain their powers, hopefully their abilities are portrayed in an enhanced form. Little Isabelle has yet to surprise us again.....Mamita knows......Namaste.

Agreed, it would have been great to see it all in one sitting, but then there'd be nothing to look forward to next week.

At first I never really trusted Isabelle. But now they are saying that she is the cure? I always thought she was evil.
