Robert loved Lisa. Lisa loved Robert. No one thought they were good for each other - Lisa's mom thought this was a phase, her father hated Robert - even their friends thought this relationship was a tad off. Under an after-sex conversation, this subject came up. Robert told Lisa to "listen to her heart, and the voices in her head." This scared Lisa - how could he know about that?

Robert was never found - experts say he was eaten, not by the swarm, but by their queen. They claim that this triggered her, along with the voices - the swarm - plotting their attack.
