Erica made a joke about her period being the week before. Derek later said she'd wear the spiked halo because she could take more pain than the rest. we'd seen in season one that pain can help werewolves regain control - so attaching pain inducing devices should have given them pause as they tried to escape. itddidn't work but that was the idea.
