I have to agree with TOC. Hodge wouldn't have reacted to the blackmail so violently if there hadn't been some substance to the threat (substance serious enough to warrant his reaction). So Hodge's motive has to be explored.
And although Lois may be naive in terms of the more bizarre possibilities - she has to realize that Hodge's reaction was over the top, given the apparent cause. That in itself should be sending alarms through Lois. Even if she doesn't believe that Clark is an alien, Hodge has a secret probably involving the Kents - a secret deep and dark enough to kill for.
