He looked at him a little confused "Immune system? What's that?

So the other didn't know about it. How interesting...
"It's something that gaurds your body.. I will show you pictures if you want", he said, wondering if Alexen would be curious enough to see something like that.

He nodded "Guards your body? So it's like armour? Yes that sounds very interesting, I would like to see pictures." he said not realizing how stupid he sounded right now.

Shiro didn't think a thing when he heard the other male. Nodding his head he made Alexen to take out some books and showed it tohim. After two hours of explaining he looked at Alexen.
"So.. do you understand now?", he asked, since it was the first time he tried to teach someone about the things he knew.

"I think so.....so all living things have this immune system? Does everyone know about this or do only smart people knowledgable in science know about it.". He didn't receive much schooling so he really didn't understand how common this information was.

"Well.. I think many people know about it but I'm not sure just how many", he said, shrugging.

"oh ok....well let's finish off this fruit and if you feel up to it maybe later we can go for a walk." he said sticking the fork into two blueberries and holding them up to Shiro's mouth.

Taking in the blueberries he nodded. Maybe he would be able to go for a walk later on. Though he wasn't that sure since his back felt quite sore. Right now he was regretting he didn't have regeneration process like Alexen did.

Once the berries were gone he picked up the tray "I'll be right back iv got to put these in the sink." he said standing up. He smiled before leaving the room and headed to the kitchen.

Shiro nodded softly while smiling. Alexen was so nice to him. It was hard to imagine how he was when still in his homeland. Well.. sure he was quite intimidating with his look alone.. yet... The elf shook his head. Anyway it was in the past so why should he think about it?
