Alright, so last night, ABC did, indeed, serve up a new promo/spoiler clip for their upcoming "Grey's Anatomy" episode 18 of season 13, and it looks heavily dramatic and extremely emotional as Maggie is seen, refusing to just let her mother die even though the outlook seems very bad. She's also seen, totally breaking down in tears in Nathan's arms, and more! As previously reported, this episode is labeled: "Be Still, My Soul."

Diane's very sick

In the new clip, they start things off with a very emotional Maggie scene. She's spotted, telling Meredith about her mom, Diane, being extremely sick right now.

After that, we see a scene that features an ambulance vehicle that ,I assume, was hauling Diane off to the hospital. Immediately after that, Diane is spotted unconscious in the hospital. Someone says: "You need to be prepared."

They're harming her

Next, we see a very dramatic scene that features Magge, telling Meredith: "My mom wants to live!" And replies with: "We're doing her harm," so it's looking real bad for her at the moment. After that, we get another very emotional scene that shows Maggie, breaking down to Nathan, crying and saying: we can beat this and what not.

She doesn't want to die

Finally, we see the clip, closing out with Diane, telling Maggie that she doesn't want to die. They also tell us that this is going to be the most emotional episode of this entire season, so that's pretty huge.

I imagine there will be a lot of tears shed while watching this one. So, if you're an emotional person, make sure you have a giant box of kleenexes at your disposal that night.

We still didn't get the big question answered in this clip, which is: will Diane be dying on us? Or will they actually be able to save her life? So, we'll definitely have to wait until this one airs to get that question answered.

One thing we do know, is it will certainly deliver the most dramatic scenes, possibly for this entire season. Be sure to check out the new clip, below, and stay tuned. Episode 18 is currently scheduled to arrive on Thursday night, March 30th, 2017 at 7pm central time on ABC. Stay tuned.
