They never touched. A hand on a shoulder, a brush of fingers as they passed a book or plate, but none of those touches held the same passion as that first embrace in the shack.
They spoke volumes though. About Harry. About the past and it's joys and pains. About the mistakes they each made. Sirius told Remus to live as if it were your last day and they fought as Sirius struggled to live in his cage.
It wasn't until that last night that they spoke about them. About that loss of touch. Sirius moved first, reaching out for Remus's hand from across the table. Snape came in then and Sirius snatched his hand away. As he stood up, he told himself that it could wait until later.
