The Frontline works for me.<br/><br/><br/>As far as getting into the action goes, Blaine is an MCPD homicide detective and Leena is a firefighter. Kinda puts them dead on in the middle of many events going on in the city, though that also depends on how many stations and precincts the city has.<br/><br/>For plot hooks specific to Blaine? I could see a member of his old marine unit developing powers and using them for more selfish means or maybe a string of strange murders that are the work of someone with powers.
