Jack slipped his hands under Ianto's shirt and tried not to giggle as the Welshman squirmed.

"Hey you're hands are freezing! Where've you been?"

"Cold Storage 4, sorting out the consignment of Jupiter Bees we received from UNIT."

Ianto frowned.

"You haven't tampered with anything else have you?"

Jack grinned innocently.

"Me? Never!"

Ianto shot him a look which said a thousand words.

"I might have looked to see if we had any Glug Worms…" Jack replied, honestly this time. "I need them for target practice."

Ianto sighed. "Oh Jack. You'll never learn will you? You're like a kid in a sweetshop, making a mess everywhere."

"Who said I made a mess?" Jack looked genuinely offended.

"I did. You will have – you always do."

Jack tilted his head to one side and pulled a face that looked remarkably like a sad puppy.

"Come on, we're going to look at what you've done! Grab a mop. Glug Worms make one heck of a gloopy trail."

Several tunnels later, Ianto strode into the Cold Storage 4 with Jack following closely behind, reluctantly swinging a mop.

"Jack..."

"What?" Jack said sheepishly, expecting trouble.

"I love you!" Ianto laughed, trying to contain his pleasure.

Cold Storage 4 was pristine. Not a single box was out of place and there was no sign of the dreaded Glug Worm trails. Ianto couldn't believe his eyes.

Ten minutes later, back in the Hub's central atrium, Ianto offered to make Jack some special coffee as a treat and as a thank you.

But Jack could stand it no longer.

"I'm sorry Ianto. I'm really sorry."

"Why?"

"The Glug Worms, they're in Cold Storage 8."
