Good Troll Hunting

lThese are quest strings that open up and lead to quests inside the instance:

strings start at 73

thanks Sprokets (below) for the opening.

start with Good Troll Hunting (from Sergeant Thurkin, Conquest Hold, Grizzly Hills)
which leads to Filling the Cages (from Samir in Granite Springs, Grizzly Hills)
which leads to Truce?
that leads to Vial of Visions
that leads to Subject to Interpretation
leads to Sacrifices Must be Made
which leads to Heart of the Ancients
which leads to My Heart is in Your Hands
which leads to Voices From the Dust
leads (finally) to Cleansing Drak'Tharon (which is a quest for inside Drak'Tharon Keep)

after doing up to Subject to Interpretation and Scourgekabob
(a single quest from Prigmon in Granite Springs, Grizzly Hills)
Seared Scourge opens,
which leads to Search and Rescue (another inside the Instance Quest)
after you do that quest (completed in the instance) Head Games opens and is doable
(use the quest item on the corpse of the second boss).

I suspect the quest name is a reference to Good Will Hunting
