I totally expect Sonny to be the first patient in the new cardiac wing. He'll get some miraculous life-saving surgery and his heart will be stronger than ever. Maybe he'll even get a heart transplant from a much younger person so that he can brag to his enemies that he's got this brand new stronger heart and will live even longer so they should be *very* afraid of him because he'll be around for many more years. Or something like that.
I'm not sure how soon Monica will pass away. I read that they're still working on writing/creating her tribute episode, so I guess they could have her pass away soon, but it will be a few weeks until they have her memorial; or they could wait a few weeks and have her memorial happen a few days after she passes away. No matter what, we know it's coming in the next few days or weeks -- they've been bringing her character in to the spotlight again so that she's fresh in everyone's mind when her character does pass aw
