1. Jill and Derick chose to enter a Covenant Marriage, an option offered to couples in Arkansas, Arizona, and Louisiana. Couples that sign a Covenant Marriage License must seek counseling prior to marriage. Should they experience marital problems, they must seek counseling and engage in a longer period of separation before a divorce can be granted.
"I signed their covenant marriage certificate," Derick's mom, Cathy Byrum, 57, told PEOPLE after Jill and Derick's wedding. "It was so special. But it wouldn't matter if they chose that type of marriage certificate or not, those two would still have a covenant marriage."
2. Stephen Jones--Derick's former college roommate and a groomsman in the wedding--approved of Jill and Derick's first kiss, which took place at the altar.
"It looked like he had been thinking about that first kiss and how he was going to do it for quite some time," Jones, 25, told PEOPLE. "He dipped her pretty smoothly, I thought. And he was able to connect on the lips – that's what we are looking for."
3. Tonight's wedding episode is sure to include plenty of surprises.
