What Is Simon's Form?

He was not dead!

"You-! How could you?! Were you playing with me?!"

Thomas suddenly went into a rage as he pushed Simon away, but then calmed down again seeing him groan in pain. He still couldn't get angry at him like he did before.

"He won't die that easily. You really don't know?"

Queen mother commented as she watched Thomas angrily turning to her.

"You knew? Is that why you just walked away without telling me? Do you two enjoy seeing me crying?!"

Before he could lose control, Simon hugged him, ready to explain everything clearly, so he wouldn't be angry or sad anymore.

"I wanted to pay off my past wrongdoings. but that doesn't mean I would leave you alone."

"...."

"Thomas...You don't know what my form is, do you?"

That's a question. He really did not know what his form was. Neither he asked nor he saw it. What is his form? 

"I don't have a form."

"Ha?"
