Oh yes, they were on different sides but naively (and Tyr knew this, he knew and did not want to stop himself) the Aesir thought that things could be okay. Fenrir did not take off his hand, nor had he shoved him or anything- that was a positive sign. Perhaps it was foolish not to fear the wolf, but Tyr couldn't. At times he could see the pup, eager and innocent eyes- more fluff than claws.
"Hands are useful, especially thumbs." The tone was neutral, but Tyr was offering a small smile. He let his hand remain where it was, no longer as concerned for its safety.
However there were matters at hand, and Tyr was not sure how much time they had uninterrupted. "You wanted to speak with me, pup. I'm listening." The silent 'what is wrong?' laced in a concerned tone hung between them, but the god held back those words.
