Although it is difficult to believe, Season 10 of "Grey's Anatomy" is just about to finish - and it promises to end in an adrenaline-pumping manner. The finale, titled "Fear (of the Unknown)" will be aired at 9.00 p.m. ET on Thursday, May 15 on the ABC Network.

As viewers count down the days to the climactic end, here is some of the most important information regarding what viewers can expect in the Season 10 finale of this hugely popular television series.

A promotion video of the show suggests that Cristina Yang (Sandra Oh) finally makes a decision regarding the offer from Preston Bruke (Isaiah Washington) and it devastates Owen (Kevin McKidd). Although Oh is leaving the show, a report in TVLine hints that Shonda Rhimes will allow Cristina to leave alive.

In fact, many "Grey" fans will be relieved if Cristina does not die and just shifts to Switzerland, as rumors have been suggesting her exit would be a massive drama point for the show and could result in her untimely death. The deaths of Mark Solan (Eric Dane) and Lexie Grey (Chyler Leigh) already continue to reel many viewers.

The theme of the final two episodes of Season 10 of this medical drama is "Farewell to Cristina." Nevertheless, life advances for the characters of the show, even as they encounter their respective trials. Notwithstanding their new set-up at work, Alex (Justin Chambers) and Jo (Camilla Luddington) are endeavoring to make things work, while April (Sarah Drew) and Jackson (Jesse Williams) are occupied with plans for their baby. The couple seems to have things easy.

On the other hand, other characters in the show will face some challenges. While Miranda Bailey (Chandra Wilson) is having problems, as the parents of her "bubble boy" patient are dejected though their son's condition is improving. Even Callie (Sara Ramirez) faces another challenge.

A synopsis of the finale on WetPaint.com hints that one of the residents is likely to be fired from the ABC show. In fact, fans should note that two residents are leaving the series. There are rumors that Leah Murphy (Tessa Ferrer) and Shane Ross (Gaius Charles) may be leaving.

While If Shonda Rhimes is already getting emotional on Twitter, it remains to be seen how the fans react after seeing the final episode of Season 10.
