How do you unexhaust a card, like a talent, after its been used? if someone could also post a page number for the rulebook, Id really appreciate it too. We spent like 20 minutes looking tonight and couldnt find it anywhere. No "exhaust" in the glossary either. Blah!

like any other card a token is normally removed from a talent at the end of the player's turn, additionally fortune points can be used to also removed tokens. This is explained in the middle paragraph of the first section of p20 of the main rule book (under TALENTS).

The only exception to this are talents socketed to the party sheet, this is clarified in the FAQ, but basically, the only way to unxehaust talents socketed to the party sheet is to use fortune points, they do not refresh automatically. Opyionally, the gm may allow a token to be removed during the rally step; it's all in the FAQ.

Talents, Rulebook pg 20, 3rd paragraph

"An exhausted talent cannot be used again until it has finished recharging. When a talent card is exhausted, the talent is placed face down and four tracking tokens are placed on the card. One recharge token is removed at the end of each of the character's turns. To help recharge an exhausted talent more quickly, a player can spend fortune points, to remove recharge tokens."
