Yoda from the AMC Board:

Babe's confession that she slept with Josh devastates JR, even though she assures JR that it's him that she loves. When JR races off, Babe begs Adam to find him because she's afraid of what he might do in his state of mind. Meanwhile, JR downs a few drinks while he waits to tear into Josh when he returns. Bianca finds a drunken and disorderly JR waiting for Josh in his room. Totally aware that JR is determined to rough up Josh, Bianca refuses to let him leave the room. Erica walks in as JR threatens Bianca, and the two women are aghast when he trips and falls out the window!

Erica finds a beaten JR laying unconscious in the ally and Josh hovering over him. Josh puts a call out to Babe, Jeff and Adam, who rushes to the hospital to check on his son. While JR is taken into emergency surgery, Julia prepares Babe and Bianca for the worst, saying there's a chance that JR won't make it. JR's family gathers at the hospital while he is still in surgery. Meanwhile, Tad promises Dixie that Emma will be a part of their lives if she ends up being their daughter. Babe makes it clear to Josh that she wants nothing to do with him.
