Nova #5 (HERE BE SPOILERS!)

This issue doesn't have the most complicated story ever written, but Sam's confrontation with Titus follows a logical trajectory and wraps up this introductory arc pretty nicely.  Moreover, Loeb ditches two of the series' more forced sub-plots by having Sam's identity revealed to his mother and by confirming that Sam's father is alive.  Sam's quest for his father promises to be a pretty decent framing device for him learning about his powers, so I'll hang with this series for a few more issues at least.
