Finnick Odair, aged 15. District 4.
Unlike everyone else, Marion doesn't try to make Finnick talk about his problems, which he appreciates.
Actually they don't really talk at all when Finnick is with the elderly Victor. They mostly sit in a companionable silence, just enjoying not being alone.
The District 4 Victors are like their own little family, Finnick is finding- always looking out for each other and supporting one another. Being part of a community that understands is a comfort that Finnick didn't realise he needed until he was inducted into it. He spends his days mostly splitting his time between one Victor or another, taking part in activities he never would have even considered doing before.
Everything was different before. It seems like a lifetime ago that he was that frustrated little boy who couldn't cope with the idea of becoming a fisherman. The simplicity of fishing seems much more appealing to him now.
Of course Mags is his favourite Victor- she'll always be his mentor and general guru on how to be a Victor, but Finnick finds he enjoys Marion's quiet contemplation just as much as surfing with Seaton, or gardening with Adrian. They spend many hours sitting together in his garden, overlooking the sea.
Marion introduces Finnick to hot drinks as well. He has a wide selection of tea leaves, herbal drinks and coffee beans. On the train to the Capitol Finnick had discovered coffee for the first time, although had been put off by its dark bitter taste. The way Marion makes it though tastes much better, and Finnick almost can't believe it's the same drink.
"Ah, the secret my boy is that you have to sweeten it up a bit," the old man says when Finnick questions him. Marion then presents Finnick with a little glass bowl full of small white cubes, gesturing for him to pick one up.
Finnick turns the little lump over in his palm, intrigued by its rough texture.
"Try that then, my boy," Marion encourages, and drops one of the white cubes in his own mug of coffee as if to demonstrate. He swirls his spoon around in a satisfying 'clink'.
"What is it?" Finnick asks. It's course between his fingers. He tentatively drops the white cube into his drink, stirs it a few times, and then takes a sip. It's sweet and Finnick finds himself now enjoying the flavour of the brown liquid much more.
"They call it 'sugar' in the Capitol", Marion is saying. "They use it in everything there. I think they even give it to the horses sometimes."
Lucky horses, Finnick thinks.
For some reason it seemed important to me to clarify that I don't actually take sugar in my own coffee, but I noticed that in Mockingjay Finnick does. Here's an imagining where that might have come from.
