Proof

 Zaos felt so relieved and alive when his mother hugged him tightly for quite a while. Still, something felt weird, it seemed that his mother shrieked a little bit. Zaos was taller than his mother already, even though he still had plenty of room for growth. Just as usual, his mother smelled like the garden of the house.

"Welcome home, Zaos," Lyra said.

"Thanks, mom," Zaos said, and then he frowned a little bit since his mother's temperature seemed higher than usual. "Do you have a fever, mom?"

"It is just the sun," Lyra smiled. "We have been waiting for a while."

"I am sorry for my delay…" Zaos said, and then he looked to his father. "I am back, father."
