And I have no idea where Tosh went. She probably got fed up with the baby and Jack being a big baby himself and needed a break from everything -- work included -- and the Doctor was there and Ianto and Jack and Emi made big eyes at him and he relented ('cause he's a softie like that, and he was a single parent for a while and understands what it's like).

They probably went somewhere really nerdy, like the Library of Alexandria.
