From what I understand he was moved out of ICU once all of the surgeries were complete and was in rehab at Craig with paralysis that may or may not be permanent and full brain functionality.

As for Shenna his family shut her out, everything wrong with Ralph's life was due to her and it was her fault that his life is ruined according to them. They screwed her over in a big way so I'm not surprised that you have not heard from her. She tried desperately for about 8 weeks to let him know that she was there for him, but they were relentless. Ralph ended the relationship.
