biancurath: I don't think Jack would really want to eat chocolate when he has a sword in his stomach. Yeah he does act like a five year old sometimes, poor Ianto.
Out of all the odd Torchwood things Jack being turned into a kid because he landed in alien goo was not something Ianto had ever prepared for. Jack seemed to have adjusted to it though. He mostly just followed Ianto around, often asking him what he was doing.
Jack stayed with Ianto at his place now, the hub was too dangerous for him. Ianto had made the couch up for Jack and moved what few possessions Jack had to the back of his closet so he wouldn't have to go back to the hub if Jack wanted his stuff.
Ianto wondered what he would do if Torchwood didn't find a solution soon, if Jack worried about the same thing he was taking a break from his worries to reach the coffee machine.
"You're too young to have coffee." Jack pouted in disappointment. "I'll make you some hot chocolate."
After Ianto finished making it Jack had gotten to the marshmallows and attempted to stuff them all into the cup. Ianto gave him a disapproving look and then took the marshmallows.
