He is quite old and only has a fringe of white hair.
The Farm Edit
He was one of the first few men who willingly came to the Farm (which would one day grow into the Black Tower) after Rand al'Thor announced his amnesty. Flinn was the first man to be tested, and Mazrim Taim determined that he could channel if taught. The reason Flinn came was because he wanted to learn how to Heal. At the recommendation of Corlan Dashiva, Flinn begins to explore his Talent for Healing.
He is one of Rand's bodyguards when he meets with the Sea Folk and makes the Bargain. Flinn has a Talent for Healing, and was able to stabilize Rand after the latter's wounding by Padan Fain with the Shadar Logoth dagger.
Flinn Travels to Illian with Rand in order to confuse Sammael and try to bring him back to the city of Illian so Rand can finally defeat him. Rand trusts Flinn a great deal, so Flinn is promoted to the rank of Asha'man.
He goes with Rand to meet the Illian rebels loyal to Lord Brend and is part of the force that attacks the invading Seanchan just outside Illian.
On arriving back in Cairhien he accompanies Rand to his meeting with Cadsuane Melaidhrin. When the rogue Asha'man attack Rand's quarters, Rand nearly fries Flinn on purpose due to his lack of trust of the Asha'man.
Cleansing saidin Edit
After the attack of Rand in the Sun Palace, Flinn is bonded as a Warder by Corele Hovian. Despite being bullied into it by Cadsuane, there appears to be true and strong feelings between him and Corele. He Travels with Cadsuane and Corele to Far Madding to track down Rand. He then goes with Cadsuane to meet with the Counsels of Far Madding when they have Rand prisoner. He pretends to channel saidin in order to break Aleis Barsalla and set Rand free.
His instinctual skill for Healing leads Flinn to discover a cure for severing, quite independently from Nynaeve al'Meara's parallel revelation. Prior to their discovery, clear back through the Age of Legends, it was firmly believed that once cut off from access to the One Power, a channeler could never touch the Source again. Damer restores channeling ability to Irgain Fatamed, Ronaille Vevanios, and Sashalle Anderly.
Flinn accompanies Rand and Corele to Algarin Pendaloan's house in Tear, where Rand recovers after cleansing saidin. He watches Lan Mandragoran and Narishma practice swordplay in the courtyard with the other Warders.
Arad Doman Edit
Flinn accompanies Rand to Lord Tellaen's manor in Arad Doman. He is sent to pick up Harine din Togara Two Winds to be Rand's ambassador. Later he is sent to the Daughter of the Nine Moons to request her to meet with Rand. He is there when Rand sends Naeff to the Seanchan, to ask to meet the Daughter of the Nine Moons in Falme. He stands with Cadsuane and Corele on the Bandar Eban walls to watch the ghostly procession that circuits the city at night. He goes with Rand to Falme, where he meets with the real Daughter of the Nine Moons, Tuon Athaem Kore Paendrag. When Rand pulls his force out of Arad Doman, he and Naeff open the gateway for the force to enter through into Tear.
Rand tells Flinn to create a gateway to the Field of Merrilor for Darlin Sisnera and the entire Tairen army. Nynaeve Heals the damage caused when channeling while saidin was still tainted, ridding Flinn of any trace of madness. Flinn opens the gateway for Rand, Rodel Ituralde, and the rest of their men to Travel through from Maradon.
The Last Battle Edit
After the Last Battle, Flinn and Nynaeve try to Heal Rand with their joined strength and extraordinary Healing capabilities, but utterly fail, not knowing Rand's soul no longer resides in his body.
