If you haven't seen the last in the current series of Grey's then you'd best reserve a space on the sofa and hog the remote, because it's heading out with a bang tonight on RTE Two. There's drama left right and centre as a big storm hits Seattle, Owen and Cristina face a familiar dilemma, and Meredith and her babba are on dangerous ground in a gripping double bill. And sure if you've seen it already, why not catch it again? Sure you'd never say no to some more Dr McDreamy, eh?
