Derek is still operating when he finds out about Meredith's current situation. Meredith is freaking out about her situation. Webber and Bailey are dealing with medical health issues. Cristina and Izzie have their own issues to deal with because of Meredith's situation. Addison freaks out when George tries to find a solution to Bailey's impromtu postponement. Overall, Seattle Grace Hospital is still under code black and the situation is getting worse.
The lads are in Lillehammer for their version of the Winter Olympics. So expect amongst other things: car ice-hockey - with Suzuki Swifts - Jeremy trying to drive the new Jaguar XK around the rink faster than a speed skater and Stig riding a snowmobile down the ski-jump. James and Jeremy compete against each other in a biathlon using an Audi Q7 and a Volvo XC90, with the loser having to eat yellow snow.
There's also a spectacular attempt to send a rocket-powered Mini down the ski-jump.
