'Grey's Anatomy' fans are losing their minds over the return of McDreamy and McSteamy

We were thrown for a loop on this week Grey’s Anatomy when Shonda Rhimes brought back some of the show’s beloved characters who have died.

In the penultimate scene of the episode, titled “Flowers Grow Out of My Grave,” Meredith Grey exits the hospital while ghosts of her past appear beside her.

Fans, who have had to mourn the loss of Derek Shepherd, aka McDreamy; Mark Sloan, aka McSteamy; George O’Malley; Meredith’s younger half-sister, Lexie Grey; Meredith’s mother Ellis Grey; and even Meredith’s dog, “Doc,” immediately took to Twitter to express their renewed grief. One person tweeted:

Some even pointed out the sad song choice:

So, why did Shonda Rhimes put us through this all over again?

The episode’s theme was Day of the Dead. After Meredith gets the news that her dad, Thatcher, is dying, she struggles with her feelings about his demise. But after having a sweet moment with a patient’s mother — who tells her that the marigold flower is said to guide spirits back to us — Meredith seems to come to terms with losing her father. After all, she has experience with losing many people she loves.
