"Hello" is a good place to start.

"Jenna," you say, "hello...it's me, Tim."

You approach and begin to get a better look at Jenna. She's become rather tall and muscular, very strong-looking, yet still very feminine as well. She's also become quite well developed (much like the others have) with great big breasts and wide hips. She looks you over, scrutinizing you for a moment before coming closer.

"Tim?" she says, "Oh...of course...Tim."

She smiles wide and comes even closer.
