Did we just meet the new McDreamy on Grey's Anatomy? If so, he may be more of a McNightmare.

The gentleman in question is Nathan (new cast addition Martin Henderson), a very handsome friend of April's (Sarah Drew), who brings an orphan boy from Jordan with massive tumors on his hands to the hospital at April's behest. And, as we quickly learn, he's got a major beef with Owen (Kevin McKidd), the nature of which will be explained on a future episode.

At the same time, it's Penny's (Samantha Sloyan) first shift at Grey Sloan, and of course she winds up on Meredith's (Ellen Pompeo) rotation. But, in case you thought their interactions were going to be the most awkward part of the day, their first patient is a pastor who accidentally sent a sex tape to his entire congregation. Whoops!

Grey's Anatomy recap: Everybody meets Penny Dreadful

Penny shows some considerable chops, and Meredith initially handles her new charge pretty well. The same can't be said for Amelia (Caterina Scorsone), who right off the bat looks as though she's going to burst a vein in her neck if she glares at Penny any harder. But as the day wears on, Meredith gets more and more nitpicky with Penny, even ordering her off a surgery in front of Webber (James Pickens Jr.) at one point.

Speaking of Webber, he and Maggie (Kelly McCreary) are treating two of his family friends, a father and daughter who have been in a car accident. The daughter is more severely injured, while the father puts on a brave face - but, he's actually just trying to hide the fact that he has diabetes from his daughter. Unfortunately, in the course of their conversation, Webber denies having any children of his own - right in front of Maggie. Ouch.

When Jackson (Jesse Williams) gets a look at April and Nathan's young patient, Kumal, he realizes the condition is much worse than April told him it was. (She even lied and said the boy's scans had been lost back in Jordan.) After performing a biopsy on the boy, Jackson discovers that his tumors are precancerous, so the recommendation is a double amputation.

But, after Nathan lets it slip to Jackson that April's nickname overseas was "The Machine," Jackson (perhaps remembering why he fell in love with April in the first place?) decides to try to save the boy's hands - but lies to him and tells them they're going to amputate in order to not get his hopes up. Aw.

The hand surgery is a success (naturally), and Jackson thanks April for bringing Kumal in. Maybe there's hope for these two yet ... but a tender moment between them is interrupted by Nathan asking April if she's ready to go have some drinks before he leaves the next morning (which, judging from next week's previews, doesn't happen). I smell trouble here.

Later, Webber awkwardly apologizes to Maggie and later comes clean to his friend about cheating on Adele. He also confronts Meredith about her treatment of Penny and lets it slip that he had reviewed Penny's record and knew that she was on the team that operated on Derek. "You were the only reason not to hire her," he lamely says to Meredith, who is not pleased, to say the least.

Callie (Sara Ramirez) interrupts Meredith and Amelia's bathroom bitchfest about Penny and tells them to stop being "mean and small" towards her. Meredith subsequently goes to the chapel(!) to meditate. Alex (Justin Chambers) finds her there, and she tells him that she's using the space to talk to Derek in the hopes of figuring out how to handle working with Penny.

At the end of the night, when Webber points out that he initially didn't want Meredith working at the hospital, since she was a reminder of the worst mistake he ever made, Meredith grudgingly admits that Derek probably would have liked Penny, and decides to keep her on her service for now. The same could be said for Callie, who agrees to start anew with Penny and makes out with her on a bench outside the hospital.

What did you think, Grey's fans? Are you liking Penny more? Is Nathan going to come between Jackson and April? And what's the deal with him and Owen? Sound off in the comments!
