With only three installments left in Greys Anatomy Season 13, were already getting jittery thinking of all the drama the season finale will unleash.

And a new synopsis from ABC only ups the anxiety!

Per Screener, heres ABCs first synopsis for the May 18 season-capper:

A dangerous patient escapes the hospital room, putting the doctors lives at risk; Alex faces a difficult decision in his relationship with Jo; Meredith has big news for Nathan.

Lets break down that tease clause by clause. First up: A dangerous patient escapes the hospital room, putting the doctors lives at risk.

If a fire does indeed break out at Grey Sloan Memorial, we imagine its this patient who starts it. Perhaps dangerous is code for pyromaniac here.

(The synopsis for the preceding episode also mentions a dangerous patient, whom we imagine is the same person.)

Next, Alex faces a difficult decision in his relationship with Jo.

One week earlier, hell attend a medical conference after making a shocking discovery, that episodes synopsis reveals.

Were guessing that shocking discovery will be the identity of Jos abusive husband, maybe the character Glee star Matthew Morrison is playing, as fans are conjecturing. (Matthews character is another guest at that conference, after all.)

So perhaps Alex will be dealing with the fallout of his encounter with Jos ex when the finale rolls around.

Then again, Shonda Rhimes always subverts our expectations, and wed bet good money she wants us to think big news will mean big baby bump just so well be caught off-guard by a season finale curveball.

But how does she expect us to sleep between now and May 18?!

Greys Anatomy Season 13 airs on Thursdays at 8 p.m ET on ABC.
