Holly here with 'hot chocolate' and a box of tissues. Yuri is 28 here and JJ is 32.

Moscow winters have always been awful – cold and unforgiving and like every last bit of happiness has been stripped from the world – but this year feels particularly brutal. Standing in his grandfather's old kitchen, and half expecting Nikolai to walk through the door telling him to get a bloody move on 'this isn't the crown jewels of the Tzar', Yuri sorts through his grandfather's possessions.

He told JJ he would be fine, sent him out to get some provisions for while they're staying in Moscow, but he's not. He's really not.

It's little things that hurt the most: a photograph from when he was a child, Nikolai's favourite jumper, a mug Yuri had painted for him when he was six. He remembers painting two (one for himself, one for Nikolai) and whenever he was sick or sad Nikolai used to make them both hot chocolate, serving them in those mugs and then wrapping up on the sofa under a huge fluffy blanket.

Tears begin to fill his eyes and before he knows what's happening they're falling too fast for him to try and stop. Not that he knows how to. Grief makes you do funny things like start sobbing in an empty kitchen while holding an old, slightly chipped mug but it keeps happening. It keeps hitting him when he least expects it.

And this is the state JJ finds him in.

"I tried to get as much off the list as I could but some packets I couldn't read, my Russian's still not great, and..." JJ tails off as he comes into the kitchen and sees Yuri. Yuri looks up at him, eyes already rimmed red. He didn't even hear the door...

JJ crosses the room to him, gently prises the mug from Yuri's grip and puts it down on the table. Once that lifeline is gone Yuri throws his arms around JJ and cries into his chest. JJ gently strokes Yuri's hair, whispering calming nonsense into his ear until it's only dry sobs wrenching Yuri's chest.

"You okay kitten?" JJ asks as Yuri wipes his eyes with the back of his hand.

He nods. "Sorry," he says. "I just got thinking and..."

"No need to be sorry," JJ says pressing a kiss to his forehead. "I'm here now, I've got you."

Yuri clutches a little harder at JJ's coat. "I don't think I can do this."

"You don't have to do it alone," JJ tells him as he brushes Yuri's fringe out of his damp eyes. "I'm here to help."

"Thank you," Yuri says, his voice barely above a whisper.

"Want me to make you some hot chocolate?" JJ asks. "We can lie on the sofa and stick something stupid on the TV and I can pretend I know what people are saying."

A lump rises in Yuri's throat again. "Yes please," he mumbles.
