As he listened carefully to to what the Doc said, he nodded and looked back at the ground with a sigh. Rubbing his forehead, he just sat there, thinking. He then slowly stood up and looked at the Doctor.
"I will stay here for a while, I think. Unless there are not other circumstances I need to go after, I am...fine here, probably."
He then reached him a card with his contact data on it.
"In case there is something...that might help, could you call me?"
He stepped away a bit after he gave him the card and walked to the door, turning around before he would exit the room.
"I am thankful for every help...I honestly hope there is a way..otherwise...*He shrugs slightly*...well..not everyone can live forever."
Speaking the last words with a rather low voice, barely hearable, he then made a move to turn around to the door, opening it.
