'Grey's Anatomy' fans are screaming all over the world last night as Meredith Grey and Derek Shepherd appear to have reunited.

The two-hour premiere episode of season 17 of 'Grey's Anatomy' aired in the US last night.

The previous season had been cut short short due to coronavirus.

Images depicting Ellen Pompeo (Meredith) and Patrick Dempsey (Derek) together and hugging on a beach have gone viral this morning.

 

But what does it all mean??

Well, if you don't want to know what happened in last night's episode, seeing this as simply a sweet reunion, we recommend you click away now.

But for those who are super curious and NEED TO KNOW why and how MerDer resurfaced, scroll down.

 

From here on, SPOILERS feature........

The debut episode of season 17 saw Meredith passed out in the hospital (possibly from coronavirus).

She has a vision of Derek - who died in the season 11 finale - on the beach, leaving us with a cliffhanger.

Annoying, right?

Well Derek is certainly not back from the dead. But he appears in next week's teaser, so it's likely he'll have some wise words for his wife before she comes to.

Now to just figure out a way to write Christina Yang back in...
