Nova #4 (HERE BE SPOILERS!)

Meh.  This series is going off the rails pretty quickly for me.  This whole issue revolves around some pretty unbelievable exposition on the part of the bad guy, who conveniently tells Sam that he's managed to create an Ultimate Nullifier.  Then, when Sam shockingly manages to use his Nova powers to their fullest extent like a seasoned veteran (and not a distracted rookie) and steal the weapon, he proceeds to "hide" it in the trash can.  Yup.  I'm not sure how much longer I'm going to be here for this ride.  I know we're supposed to be wondering where Sam's dad is and why he decided to go after Titus in the first place, but I spent most of this issue just wishing that Richard would return.  Sad, but true.
