One Tree Hill was filled with plenty of predictable storylines this week, but also delivered one with a surprising twist that had me itching for future episodes.

Has there been a more obvious ending to a weekly plot than Millie's live, on-screen tirade being a ratings hit? As they played it harder and harder that her social commentary was undoubtedly going to get her fired, it was easier and easier to see that the fans were going to love her. The predictability didn't stop me from enjoying the ride, though. 

For the first time in a while, Mouth came out smelling like roses. His rant, which Millie eventually stole, was both entertaining to watch and completely justified. Why would they spend so much money on those street signs?

"The Smoker You Drink, The Player You Get" also gave us predictable storyline number-two: Kid is bad at sports. Adult tries to help him. Adult figures out that kid needs glasses in order to perform well. 

While I normally would rag on a show for pulling this played-out stunt, I will never tire of Chase and Chuck hanging out. Chuck went from bratty little jerk to sensitive loaner with such ease that it was hard for Chase and the audience not to love him.

Because it became clear that Brooke was going to be adopting a child from a pregnant woman, many have been assuming that Haley and Brooke would have their babies at the same time. That seems to be the case, as both Hales and Chloe went into labor simultaneously. Kudos to those who called it weeks ahead of time.

Of the two mamas-to-be, Haley's plot was far more entertaining. Don't get me wrong, deciding what color to paint the baby's room can be very exciting, but Haley tricking her friends into thinking she was going into labor over and over again was flat out classic. When fooled by Haley, Quinn and Brooke went the normal crazy route, but that wasn't as funny as Julian just passing out as soon as he heard. 

Naturally, Nathan and Clay would try to act all cool because they knew she was joking, but once she turned up the dial and claimed she actually was going into labor, they panicked like the rest. Score one for Haley James Scott.

Finally, the Nathan/Clay/Ian/August story was both the most interesting and the one that kept me guessing right up to the final seconds. It was fun watching Nathan and Clay use their beer pong skills to get Ian to sign the contract to become a client of Fortitude, but as soon as they started talking about a morals clause, I knew something was up. I assumed it was going to lead to Ian passing out drunk, or getting caught with a prostitute - you know, something out of the Charlie Sheen playbook - but I wasn't expecting the car crash on the bridge to be brought into play.

So Ian Kellerman was the driver of the car that slammed into Jamie and the gang, shoving them off the bridge and into the river. This dude is obviously a jerk, and once Nathan figures it out, he will no doubt want to void that contract. But is this why August Kellerman didn't want Nathan to represent his son? Did he know what Ian did that night, and to whom, and determined Nathan might be able to put the puzzle pieces together and send his son to jail for a long time? 

If that's what show-runner Mark Schwahn, who also wrote the episode, was trying to demonstrate, good job. Placing that dialogue between August and Nathan that early in the episode definitely made you forget it until the very end when Nathan found the smashed car with the empty liquor bottles.

Did you foresee where these storylines were going to end up? And are you excited to see what will happen between Ian Kellerman and the now-enlightened Nathan Scott? How excited are you for double babies?
