Miniver... just doesn't want to look at anyone right now. He replies to Soren with a noncommittal shrug and curls himself closer to Toki. Hearing Toki called 'grandpa' is just another kick to the gut -- not just because it makes HIM feel old, but because of things he's heard before about Toki's mortality.
He feels a little like he's going crazy right now. In his whole life, this is one of the hardest things he's ever had to do. He wants to cry. He wants to be sick. He wants to run away. He wants to just not be anymore. And he can't find the train of logic where this is all illogical enough for him to be able to hold onto it and think himself out of this.
Finally, when there's a pause in the motion and talking, he forces his eyes up to look at Teja, winces, and curls into Toki again, gripping his arm tightly.
"I can't--" he begins to answer Teja's request for no one to feel bad about this, and melts into a more general statement, quiet and muffled against Toki' arm. "I can't do this. I don't know what to do. I've never known what to do. I'm so... so sorry."
