We hope you kept a receipt for those wedding gifts, “Grey’s Anatomy” fans, because it looks like you may just be returning them after Thursday night’s episode.

A sneak-peek video for the Season 12 finale of the hit ABC series teased trouble in paradise for Owen (Kevin McKidd) and Amelia (Caterina Scorsone) when it revealed the soon-to-be bride was spending the morning of her big day locked in Meredith’s (Ellen Pompeo) bathroom.

“She’s fine!” Meredith tries to console a worried Maggie (Stephanie McCreary) in the trailer as they sit outside the locked door. “You have no idea how many people have locked themselves in that bathroom. They’re always fine.”

But since this is “Grey’s Anatomy,” we're not sure just how “fine” Amelia really is. The actress dished to TVLine that the reason she ends up sobbing in her sister-in-law’s bathroom is that an “unfortunate series of events” unfolds involving her family, causing Amelia to go into a “tailspin.”

“She was gung ho to go for [getting married], but the morning of the wedding, she’s not getting the celebration and the party that she thought she’d get by becoming this adult who’s getting married,” Scorsone stated. “So she’s disappointed and feeling very betrayed."

Not only will Amelia have to deal with the deception from the Shephard brood on her big day, but she’ll have the concern of the weather weighing heavy on her shoulders as it begins to pour. But rain won’t be Amelia’s last issue. Little does she know that an uninvited guest is set to crash her wedding when April (Sarah Drew) goes into labor in the middle of the ceremony. Needless to say, the odds are stacked against the bride-to-be, causing audiences to question if Owelia will tie the knot on Thursday.

McKidd teased audiences on Twitter, stating that his character is overdue for some happiness, which is why he’s excited for Owen to exchange vows. When a fan called the actor for spoiling the finale, he replied with an ambiguous tweet.
