48 Hours

After Mark breaks it off with yet another woman, he shares his personal theory -- explaining that couples know within 48-hours of meeting if they want to be together. Not surprisingly, everyone agrees that they knew they had met their soul mates within that timeframe except Whitney. Trying to prove her wrong, Alex takes Whitney on a trip back to 2008 and the night they first met. While reminiscing, it is discovered that Lily and Roxanne needed some special help to discover that they might actually like each other.
