but where is the comma?

"just agree you will have a hug" is a pretty solid search term for fun with. but it really makes me wonder: is it, "just agree, [and subsequently] you will have a hug," a manipulative yet potentially very effective bargaining strategy? or is it the more last-ditch-flavored, "[if you're not going to agree to anything else,] just agree you will have a hug"?
