Ok....updated with actual text in the post.
My BIL passed away late last night. My mom called to let me know. HH and I went to the hospital. My sister did get to be there when he passed (which was a huge worry to her that he would die alone). He took two gasps of air, and then stopped breathing. It was very quick and peaceful. My mom didn't even notice that he had stopped breathing until he looked over at my sister and saw she was crying. I'm glad I got to be there with her until the end.
