The season finale of The Bachelor airs next Monday, and fans are anxious to find out which of remaining women will win Sean's heart. Will it be Catherine, the goofy graphic designer from Seattle? Or will he choose Lindsay, the substitute teacher who introduced herself while wearing a wedding dress? The two women do share some traits. They both pride themselves on being funny, goofy pranksters who keep Sean on his toes, and they're obviously both lovely people. (No Tierraists made it through the screening process.) Aside from that, though, Lindsay and Catherine don't have all that much in common. So who will Sean decide on? His choice will reveal a lot about him.
