If Mark says it is fine, it is fine. He would know his own mind and comfort after all. Leonardo obviously responded well to his attempt to check in with everyone. It informed him of what was happening, and gave him an idea of how to help others, which he is doing his best to fulfill.

Leo gets his coat as well. And his hat and his scarf. He overdresses for the weather outside, or it would be overdressing if he isn't actually cold, but he is. All of the time. He despairs of ever getting used to it. He does look wide eyed at Mark at that date. Two and a half years. That is slightly alarming, yes. While he doesn't hate the situation he's in, that seems so long to be gone from his projects, from his country.
