"Elena thinks we just need to keep imprinting from happening outside of controlled circumstances at all, but then unimprinted guys couldn't go anywhere, see any girls besides vampires and women who can't have kids - we're pretty sure those don't get imprinted on - and family members. It's not even impossible to imprint on a puppy, turns out, and then the puppy doesn't activate when she's old enough, so we're all pretty worried about Denise now. Her wolf most of all."
