I don't really care for Jacob that much, but this a scene that I've always wanted to see written: Jacob's wedding with Nessie. Now, I'm not the best writer in the world, so please don't judge too harshly:

Renesmee sat on the living room couch with Jacob's arm tight around her waist. Beside them sat Alice, a big pile of bridal magazines in her lap.
"I just can't believe Du two are getting married already," she gushed, flipping through the glossy pages of a Modern Bride issue. "It seems like just yesterday Ness was still in diapers. Oh, where has the time gone?"
Renesmee rolled her eyes.
"Anyway," Alice said, "have Du two decided on a location yet?"
Jacob nodded. "La Push Beach."
Alice raised her eyebrows. "Are Du sure?" she asked. "I bet I could find Du somewhere prettier..."
"No, no, we're sure," Renesmee insisted. "La Push Beach."
"Yeah," Jacob said. "Sam and Emily got married there, too."
"Well, alright," Alice agreed, though she didn't look too pleased. "Now, what about flowers?"
Renesmee thought for a minute, pondering all different kinds of Blumen in her mind. "Hmmm...what about calla lilies?" she finally decided.
"What color?" Alice asked.
"White."
"Then white calla lilies it is," Alice agreed.
"What about the dress?" Renesmee asked.
Alice smiled with excitment. "I already have it," she said, "and it's absolutely gorgeous. I'll Zeigen it to Du if Du want, but Jake's gotta leave."
Jacob was already halfway out the door before Alice could finish talking. "This is female stuff, anyway," he muttered on his way out.
Alice dashed upstairs to get the kleid and returned in only a matter of seconds.
"Wow," Renesmee said. Her eyes lit up as soon as she saw the dress. "It's beautiful, Alice."
