Talbot

Talbot is an old man who has been working for the Vongola longer than anyone can guess. They even say that he has been working for the Vongola since the time of Vongola Primo. In the Vongola Primo Drama CD Extra, this is proven to be true as in that story, Giotto revealed when they are having a dinner together, that he had asked Talbot to make the Golden Pocket watches as proof of their friendship that each of them possess. After the Vongola were defeated by the Simon, Talbot appears and offers to fix the Rings. He states the risks of such an endeavor could potentially destroy the rings completely, in which Tsuna accepts. After a bit of work, he brings the rings back in a completely dead-like state. When everyone was down, he asks the extent of their resolve and to light the flames, warning them that a weak attempt would destroy the souls in the rings for good. Tsuna, Gokudera, Hibari and Ryohei all manage to awaken the new Vongola Rings' form, the Vongola Gear. Talbot is mentioned to have created new Varia Rings, the payment being Mammon's entire fortune.
