"He always had a smile on his face," Goldman said.

"As I was going to bed one night, it popped in my head: 'Google it. Google what you know,'" said Walter's mother, Erzsi Gemzsi. She typed in "Ryan Lake in the Hills brain tumor."

The Facebook page was for the Ryan Lamantia Foundation, a nonprofit that Ryan's family formed after his death. The organization raises money for pediatric brain tumor research and holds an annual toy drive near Ryan's birthday to restock his beloved playroom at Children's Memorial Hospital.

In November, Walter and his mom saw a Teenage Mutant Ninja Turtles shirt at a mall, and Walter had to have it. It sparked a renewed mission to search out Ryan.

Though they saw each other only a handful of times after that, Walter never forgot Ryan.

"I have wanted nothing more than to talk to (Ryan's) parents and tell them (their) son is my hero. … My trips to (the hospital) were always dreadful, until the day I (met) Ryan."

Ryan went through a period when he didn't want anyone, family or friends, to see him lying in the hospital bed, drains coming out of his head. But soon enough, the toddler who just wanted to be a little boy found a way to make it through. He kept his spirits high, even after he suffered two strokes, hearing loss and endured 14 surgeries.

For the past few years, Walter, who lives with his family in Elgin, wondered what had happened to his little buddy.

Ryan's initial diagnosis in February 2003 was almost cruel. The doctors told his family he had a "sugarcoating" of cancer throughout his brain and down his spine. The first round of chemo landed him in the intensive care unit, nearly killing him.

Ryan had died on Sept. 8, 2005. He was 6.

Walter wasn't the only person who recalled Ryan's perpetual effervescence.

Walter Wetzel had met Ryan Lamantianearly eight years ago in a hospital waiting room. Both were very sick — Ryan with brain cancer, Walter with leukemia. Walter, then 9, began making silly faces at the little boy sitting across from him.

"I just bawled and bawled and bawled," she said.

Ryan's mom's eyes filled with tears as she read Walter's post.

Walter and his family have been in touch with the Lamantias for the past few weeks. Ryan's mom sent Walter one of her son's well-worn Ninja Turtle toys, which now sits on the teenager's dresser.

After such an immense loss, Walter's words were the best gift she and her husband, Todd Lamantia, could have hoped to receive.

Walter also had a chance to meet Ryan's sisters: Alyssa, 8, who wasn't even a year old when her brother was diagnosed, and 16-month-old Sarah Ryann.

Without so much as a last name, Walter asked the hospital staff to track down a number or address, but privacy laws prohibited the staff from giving out information.

It was the start of a friendship that would blossom during other hospital encounters over the next few months, but they would lose touch after Ryan transferred hospitals. Mary Lamantia (Ryan's mother)'s memory of Walter faded during the years that followed, a time of needles, MRIs, chemo and radiation.

"It hit me pretty hard," Walter said. "I was crying for a week straight."

When she picked up Walter from school the next day, she broke it to him.

"I don't even think there's words to explain the feelings we have that our son made such an impression on somebody," Lamantia said. "It made us so proud."

"We always knew (Ryan was special), but to hear it from somebody else, it really means the world to us," said Todd Lamantia, 39, a coffee roaster in Huntley.

At the hospital, Ryan's parents held his hand and tried to ease the pain. The playroom became his haven. He carried Buzz Lightyear around with him, spoke incessantly of the band of crime-fighting turtles and channeled Spider-Man every way he could.

"I can close my eyes and see him coming down the hall, shooting his spider web at me," said Dr. Stewart Goldman, medical director of the hospital's neuro-oncology department, who treated Ryan.

Mary Lamantia was nervous as she put out the chips and salsa in anticipation.

Much to her surprise, a link to a Facebook page for Ryan came up. Finally, they had found him. But when she clicked her mouse, the news was devastating.

Soon after, Ryan, who was 3 at the time, made his way into Walter's chemo room and chatted about going home to change into his Teenage Mutant Ninja Turtles costume and ride his Big Wheel to his cousin Catlyn's house.

"He was a little superhero," said Wendy Stellpflug, a nurse at Children's Memorial Hospital and the brain tumor coordinator.

"I finally had a friend I could relate with," Walter said. "I thought of him basically every day."

看到年仅三岁的莱恩都能乐观地面对自己的病情，，每天开开心心地活着，沃尔特不禁想：“我有什么可难过的呢？毕竟，我的情况比他的还是好多了。”

"It took me about half an hour, but right before I was going to bed, I said, 'I remember who he is now,'" said Todd Lamantia, 37, of Lake in the Hills. "Ryan … just walked into Walter's room and started talking to him."

Meeting Walter for the first time, Sarah Ryann studied him from afar. After he made a few silly faces at her, she ran as fast as her tiny legs could carry her straight into his lap.
