During her junior year of high school, Jessie Russell was diagnosed with Lupus.

But she hasn't let that affect her doing the things she wants to -- like running the Boston Marathon.

But around mile 14, she started to fade. Knowing she'd be upset if she was unable to finish, her older brother, Jeffrey, who had been following her along the route taking pictures and yelling encouragement. He ran into a toy store and bought an umbrella to hold over her head and block the sun.

He told her: "If it’s just the sun, I don’t want you to stop. I can be your medical tent. I can be your water stop. Don’t worry about any of that."

The two of them crossed the finish line together. That's a pretty awesome brother.
