The Dragons full-back was born in High Wycombe and lived in Solihull during his childhood but was brought up a proud Welshman thanks to his father.
He started in the agonising 24-17 opening defeat to Australia last Wednesday and will pull on the number 15 jersey once again against England.
And he remains confident that Wales can still top Pool A by beating England at the Avchala Stadium on Sunday (5.30pm BST).
Talbot-Davies said: “Australia was a tough loss to take but it’s a five game tournament for us so we have to forget about it and move on.
“On another day we could have come away with the win. In a vast number of areas, we played very well it was just a few little things and some errors that cost us.
“We need a little more patience and accuracy, especially in their 22, a number of times against Australia we just didn’t take advantage of our opportunities.
“We’ve had the review and now all eyes are set on England. There were definitely positives to take into the England game and we’re hoping to get that W.
“Despite the loss to Australia we still definitely have a chance of getting out of the group. The main objective, as it was coming into the tournament, is still on winning it.
“We know what England are like, we’ve played them before and they have lots of individuals and good players, and they throw the ball around so we’re expecting a tough challenge but we’re confident and excited.”
Talbot-Davies was picked up by the Welsh Exiles programme and from there he has never looked back.
He has thoroughly enjoyed the opportunities it afforded him, including a development contract at Newport Gwent Dragons and recommends it to any exiled Welshmen.
Now he is aiming to have the last laugh over his childhood friends in Solihull. Talbot-Davies said: “There’s no split loyalties in the family, they are all backing Wales.
“If it was not for the Exiles, I wouldn’t be doing any of this so I thoroughly recommend it to any Welsh qualified player living in England.
“My first year at the Dragons has been great, there’s a great bunch of boys there and I’ll hopefully get a few more opportunities next year.
“But for now all my focus is on the World Rugby U20 Championship. Individually I just want to start as many games as I can and do my job for the team as well as possible. This is my only shot at the U20s so I want to make the most of it.
“I always supported Wales, I got plenty of stick and was always in the minority – hopefully we come out on the right side on Sunday.”
