For those who've lost count: the couple first hooked up at the start of Season 1, but broke up by the end of the season. They reunited in Season 2 and split again in the middle of Season 3, but quickly reconciled... right before ending things again in the season finale — when he trashed her room and stepped on her glasses.

They again reconciled during the current fourth season, set in Florence, Italy. It's unknown if cameras caught their most recent break-up for Season 5, which filmed in Seaside Heights, N.J. and wrapped in August.

Do you think Ronnie and Sammi will get back together? At this point, do you care?
