Ned has had
a rough arrival, but it is small mercies that at least there is
one man here he feels he can trust to say -- not his truth -- but something akin to it. It's take him a while to realize that against all expectations, he is dealing with all the possible benefits and disadvantages of being alive, the most important one being
not being able to get back there.
His mind has been going in infernal oops of what ifs and maybes, but those only match his foot steps as he searches the Mansion for his family.
If the Stark line is entirely extinct, then they must be here. Robb is there, he was told, but he's hoping any one of his sons might be around, Jon excepted. He figures he might as well find his wife, his sister and brother, his best friend. His face is stony and expressionless. Something in him has died inside, and will remain so, for a very long while.
The fact that Sansa and Arya may still be alive has occurred to him, but his despair smothered hope as soon as it appeared. He was never more relieved to have allowed Jon to take the Black.
