We've got pretty earth-shattering news: Jake McLaughlin checks into Seattle Grace as Alex Karev's brother during the 19th episode, set to air some time in April!
Why is this so earth-shattering? Well, it's the first time we'll meet someone from Karev's family and spoilers also tell us that during this episode, Izzie will also be making her return to Seattle Grace!
Jake McLaughlin will play Karev's younger brother and will check into Seattle Grace as a patient. No spoilers yet on what he'll have and how sick he will be. We'll make sure to post the spoilers as soon as we get them, but for now, check out the pictures of the two Karev brothers and see if you can spot the resemblance between the two!
