After the attack of the water monster, Teegra stabs the last sub-human with a very pointy stick. As she stabs, we see the stick remains lodged in the chest of the sub-human. In the next shot, as she falls on her back recovering from the attack, the stick is back in her hand.
Darkwolf rescues Larn from Nekron's iceberg, then both head to Fire Keep. They proceed to convince Jarol to lend him the Dragonhawks so they can return to the glacier to rescue Teegra and kill Nekron. Why didn't they simply infiltrate the glacier while they were still there? After all, Larn got close enough to fire an arrow at Nekron. Darkwolf could have killed him there, instead of wasting time heading back to Fire Keep.
