Over the past 4 days I knocked out the 2nd half of Smallville season 3 and am on the verge of finishing all of season 4.
Whoa Nelly, season 4! Is it me or did it suddenly get VERY HOT in here? It’s Senior year at Smallville High and hormones are raging. It couldn’t be more obvious that the executive producers of Smallville made a conscientious effort to up the sex appeal year. There is a lot of skin, a lot of hot guest actresses, a bizarre taboo relationship, and yet throughout it all, Lana & Clark remain chaste virgins. Wow, this show really is a fairy tale.

How old are you again?
Speaking of taboo relationships, dig this:
Lana goes away to Paris for the summer between her Junior and Senior year of high school. While there she meets Jason. Jason, meanwhile is a college student whereupon returning to the States he eventually takes a job as assistant football Coach at Smallville High. Umm kay… All the while he and Lana are having a relationship on the DL. Umm kay… Teacher/student relationship, whatever. Of course they eventually get caught and Jason is fired from his position. Really, that’s all? Much later in series 4 the issue of whether J&L had actually consummated their relationship finally got raised. “What!?” Lana says. “Me and Jason? NO! I’m still a virgin.” Umm kay…
I found this entire plot thread really hysterical and disturbing at the same time.
(Fine, I just did some quick research on Jason Teague via the Smallville wiki and oh how convenient. Apparently during the s4 premiere when we are first introduced to Jason’s character, as well as the ‘relationship in progress,’ it is mentioned that events are taking place the day before Lana’s 18th birthday. Oh how convenient… Umm kay.)
