I noticed something about responses, and these two cards, in my first couple of plays. Before I get into specifics, there's a general question : when playing multi-player, how careful are you going to be about the rules? Will you back-up and do-over in a case like below? Will you just stretch the rules a little if the end result is the same?
Theodred : Response: After Théodred commits to a quest, choose a hero committed to that quest. Add 1 resource to that hero's resource pool.
Aragorn : Response: After Aragorn commits to a quest, spend 1 resource from his resource pool to ready him.
Keep in mind that responses are supposed to be used immediately.
Situation 1 : Quest phase; Aragorn has a resource token, and you want to use both him and Theodred to quest.
Correct play: Aragorn exhausts to commit, and you spend his resource to ready him. Theodred exhausts to commit, and gives Aragorn 1 resource.
Incorrect play with same outcome : Theodred exhausts to commit; Aragorn exhausts to commit; use Theodred's ability to give Aragorn a resource; spend that resource to ready Aragorn. Incorrect (I believe) because Theodred's ability has to be used the moment he commits to the quest, and instead it was used later.
In this next situation, this nit-picky timing issue really matters.
Situation 2 : Quest phase, Aragorn has no resources, and you want to use both him and Theodred to quest.
Correct play : Aragorn exhausts to commit. Theodred exhausts to commit, and gives Aragorn 1 resource. At least next turn Aragorn will be able to both quest and fight, but this round Aragorn is exhausted.
Incorrect play : Aragorn exhausts to commit. Theodred exhausts to commit, and gives Aragorn 1 resource. You spend Aragorn's resource to ready him.
Another incorrect play : Theodred exhausts to commit. Aragorn exhausts to commit. Theodred gives Aragorn 1 resource, and you spend that resource to ready Aragorn.
Moral of the story : keep a resource on Aragorn if you want to use him twice per round!
