Lan Wangji bestows a fond little look down upon Magnus. He doesn't precisely relax into this partial embrace, but he shifts into it, to make it clear that it is welcome. It's as he said to Nightingale, once, months ago: if Wei Ying had not arrived, he and Magnus would not be speaking now. Lan Wangji isn't certain what would have become of him by this time, but he might well still be in the woods, burning through his qi, desperate to force his way through the fabric of reality. It is one thing to grieve a dead man and another to endure a separation from a living one. It would be cruel, however, to say something like that to Magnus, who is without his Alex. So instead, he only nods, and then asks, "You are still caring for yourself appropriately outside?"
