Three times. Three times while Eteri had been pressing herself up against his back, her arms wrapped his waist, Nevin had nearly turned around and - done something inappropriate. Instead he had nearly cut himself or smashed a finger as he worked on preparing the food. After she had sat down with a loud huff - and bumping him and making him run into the counter top with his stomach and just below - he was able to focus on the food at least a little more and stopped injuring himself.
Once she was sitting down, he was able to mix the chicken and herbs together, coating the meat in the spices and herbs before setting them into a pan to start simmering with some lemon juice. It would take a little bit to cook like this, but it should be worth the wait. He took the other chair and moved it across the table from Eteri,
putting the solid wood between them as a defense.
Thankfully she asked about something that wasn't - distracting, so he was able to focus on that. He leaned back in his chair and ran his hands through his hair as he huffed in thought.
"Well. I've already learned in the past that mine will react to my subconscious desires if you am not alert and aware - I actually found out I could feel with them when someone grabbed one while I didn't know they had slipped out. It's possible that, well, while yours were rubbing me I wanted to reciprocate - ah, return the act - even thought I was asleep. I have no idea why yours came out though, and it's clear you couldn't fell them. And no, I can make them come out from a lot more than just my hand." His left hang came up and gently traced a finger along his skin, following one of the myriad red lines that were visible on his chest.
"I can actually make them come out pretty much anywhere from my skin. And they can act as needled, or as whips, or as ropes, or to make me stronger." He lifted his arm up higher and the Crimson threads slid out of his skin and wrapped around his limb, coating it in red. Then he reached out his coated hand to her, to let her feel the smooth and almost slick surface.
"If I want to I can make them a bit sticky as well, makes it easier to grab things with them." Of course, he waited to say this until she was experimentally poking his red hand with one finger, and he shifted the threads to their adhesive state with a grin. Only for a moment though, to give her resistance when she tried to pull her finger away - too long and she might have hurt herself.
This, this was safe. Talking to her about his nature from across the table was safe and good.
