I thought they had a plan for season 4 - but after the finale not everything added up.

Here is what's missing:

• Where are Addy, Red and Dr. Sun? (Just written out?)

• What happened to the people from the convoy and other people who just vanished? (I thought they were already victims of black rainbow - but apparently it wasn't launched back then) (A test?)

• Was Dr. Keller a good or a bad guy? Was Warrens Mission to kill or save everybody?

• Does NewAmerika exist? (President says no) (Maybe that was the answer)

• And what did the glasses guy in the end want? Stop Warren to kill or heal everybody?

• Didn't Warren pull more then 2 cylinders out of that lab cabinet? And even e few in earlier episodes? (Maybe the continuity teams failure ;)

• And what happens to the world now - with the mixed up containers in the drone? (Ok, that is the cliffhanger)

• Red Murphy? Ok why not ;)

The season started strong and had a few very good and funny episodes - but I hope they weren't making their story up - on the go. We'll see in season 5.
