The day of the wedding, Cassandra and Vala were helping Sam get ready for it. Sam was a nervous wreck.
"What if he doesn't really love me? What if this isn't right? What if-?" she was babbling.
"SAM! CALM DOWN! NOW! AND STOP TALKING!" Cassandra yelled at her. Sam nodded and stayed calm for the rest of the time.
Jack was ready for this day. The wedding was being held in the gate room. Every member of the SGC was there, along with Bra'tec and Thor. He saw Teal'c walk in with Cassandra, the maid of honor, and Daniel walked in with Vala, another bridesmaid. Then he saw Hammond walk in with Sam.
She was beautiful in her white, off-the-shoulder dress on. She saw him and smiled. He smiled back. He was so wrapped up in her beauty that he heard no one speaking until he heard, "Jack O'Neill, do you take this woman as your lawfully wedded wife?"
"I do."
"Samantha Carter, do you take this man as your lawfully wedded husband?"
"I do."
"Jack O'Neill, take this ring and say 'With this ring, I thee wed'"
"With this ring, I thee wed."
