Regardless of her opinion of Herc in general, Teren isn't about to side against him while there's an ogre to kill. She casts him a brief glance when he cedes to her shout, acknowledging and thanking him without words, and then launches onto the creature's back to plunge her needle-like blades into either side of its spine, right where its head meets its neck. It doesn't die, but it stumbles, confused, directly into Herc's shield, opening its limbs to Lena's ministrations.
