"Luxa, it's your grandpa," said Gregor. It seemed like the best and most important thing to say at the moment. "It's your grandpa."
Luxa blinked. A tiny tear formed at the corner of her eye. A battle took place on her face as she tried to stop the feelings rising up inside her.
The feelings won, and to Gregor's great relief, she ran into Vikus's arms.
