Denny is alive! Well, not actually . . . but the beloved “Grey’s Anatomy” character who died in Season 2 has been resurrected in a series of episode flashbacks now available online at CTV.ca.

The heartbreaking storyline between heart patient Denny (Jeffrey Dean Morgan) and Izzie (Katherine Heigl) is just one of the many key moments highlighted. The quick cuts recap major plot points and twists from the first five seasons in one to four minute clips.

Now that Meredith Grey (Ellen Pompeo) is happily married to Dr. Derek Shepherd (Patrick Dempsey) and a mom to baby Zola, it’s hard to remember when she wasn’t so happy. But in Season 1, things got off to a rocky start when Meredith realized the random guy she took home from the bar turned out to be Shepherd, an attending neurosurgeon -- and her boss.

That wasn’t Meredith’s only problem that season.

Back then, Dr. Miranda Bailey (Chandra Wilson) was even more hardcore then she is now (we know, it doesn’t seem possible).

“Dr. Bailey, I was hoping to assist you in the O.R. today, maybe do a minor procedure?” asks a timid Meredith Grey.

“That’s not your job. Do you know what your job is? To make your resident happy,” says a gruff Bailey, as she takes the cup of coffee Grey is offering. “No one holds a scalpel until I’m so happy that I’m Mary freakin’ Poppins.”

Even though we know Dr. Bailey eventually softens her stance, it’s great to see Meredith, Cristina Yang (Sandra Oh) and the former interns Izzie Stevens and George O’Malley (T.R. Knight) sweating it out.

Speaking of George, we didn’t realize how much we missed this goofy and loveable doctor, who passed away at the end of Season 5 after being hit by a bus. Remember when he and Callie (Sara Ramirez) got married? Or that awkward scene when he slept with Meredith? OK, maybe there are some things we don’t want to remember…

And then there was Addison (Kate Walsh), who arrived with McSteamy (Eric Dane), to shake things up at Seattle Grace. Even though we were just as unhappy as Meredith to see that Derek was married, we admit we were very sad to see Addison eventually go.  And she wasn’t the only one who left. Dr. Burke (Isaiah Washington) made his exit shortly after his failed wedding to Cristina, leaving the door open for new doctor (and new love for Cristina), Dr. Owen Hunt (Kevin McKidd).

As well as all the relationship drama (we’re looking at you Alex Karev), one of the most intense episodes ever is featured in Season 2 when Seattle Grace calls a “code black.” It’s the only time this call has ever been made and it’s up to Meredith to make sure the bomb doesn’t go off. The only problem is the explosive device is in a patient’s chest ...

Once you’re all caught up, you can watch the latest episode from the current season, now online at CTV.ca, and get ready for the much-anticipated season finale Thursday May 17 at 9 p.m. ET/PT on CTV.

We’re not holding our breath but it sure would be nice if Denny came back for the finale (no, we will never get over him).
