This could potentially have spoilers, so be forewarned. (I'm not sure if they are actual spoilers but I found something that is worthy of discussion.) Ok, hopefully, I have enough filler. . .Ok, so we know that Michael has been communicating with somebody on the computer. We also know that the year is now 2006. So why would imdb be listing the actor that plays Walt as off the show? (They also have Shannon and Boone off the show.) Do you think imdb has some inside info? Or could it be a case of "We didn't like the guy who played Caleb on Desperate Housewives so we replaced him"?
Three is the perfect number.
