Rob Hawkins is Beth McIntyre's ex-boyfriend in Cloverfield. He's also the recently elected vice president of a Japanese company. He was a close friend of Beth's since they were in middle school... but after he slept with her less than a month before the monster attacked New York, he didn't speak with her for awhile. Bad form, Rob.
