Hallmark-style movie with a kid dying of cancer and a possibly magical stranger that comes to stay with the family
I have hazy memories of a movie I saw as a kid that might have been from the 90s or early 2000s. It's a sappy emotional movie, Hallmark-style, in live action. There are two boys living with their mom after their dad died. The youngest has a name like Bobby or Tommy. A man comes to stay with them and the older kid thinks he might be an angel or magical in some way and that he can make miracles happen or grant wishes. Then the little boy (Bobby?) gets sick and complains that his stomach hurts. Mom takes him to the hospital and learns he has cancer. The scene that has haunted me since childhood is when she is doing laundry or something in the dark house after the boys have gone to bed and the man comes to check on her. She tells him, "Bobby has cancer. Life should have a rule: only one tragic death per family." She cries in his arms. I don't remember whether the man actually made any magical things happen or whether Bobby got better. I think they watch fireworks together at one point. I'm pretty sure the man leaves at the end of the movie, or talks about leaving. I don't remember if he was actually magical in any way or if the kids just thought he was. Now I want to find this movie and watch it so I can confirm that I didn't imagine the whole thing.
This is not Angels in the Outfield or A Monster Comes. That's what Google keeps trying to gaslight me into believing.
