On the Lizzy/Bricks dynamic -- I wonder if there's something going on between them behind the scenes. If you think about it, Lizzy has no idea if Saul's alive or dead. She wasn't at the Tower when MPK returned from the Colony, so she may not even know that they know it exists. She's known Bricks longer than the original gang, knows that he's there to protect her and the baby -- hence, it would be silly of her not to form a relationship with him on the account of "cheating" on Saul.

I'm a little scared at what will happen once Saul & Co. bust in and give the colonists weapons for the coupe (if the plan goes successfully). Since the Mallers have been treating Lizzy well, most people would see Lizzy as one of the Mallers. Saul & Co. will obviously see Bricks as being aligned with the Mallers. All it takes is for one person to encounter the wrong person at the wrong time without having the whole story -- and BANG. Bad times.

I'm most afraid of Saul coming in and hurting Bricks. As much as Lizzy loved Saul before, I don't think she could easily forgive him if he killed Bricks, reagardless of whether something was going on between them or not.
