The others didn't stop Heart. Like the Child, he quickly walked up behind the group and tried the same thing.
No one paid him any mind, nor did anyone react in any special way. The person he pushed over simply trembled back to their feet, a few pieces of their body falling off in the process.
So, he walked over to the bonfire. He first glanced at what was cooking in the pot, then straightened up and pulled open the front of his robe.
He took out a small carving knife and slashed it across his chest twice.
He put the knife away, but no blood flowed from the wound. Instead, he used both hands to forcefully pry open the gash in his flesh and thrust one hand inside.
He seemed to have found something. With a hard tug, he pulled out a bloody heart. Veins and blood vessels still connected it to his body; he hadn't torn them loose.
