The nickname opens a wound long since closed; but not healed. She has to swallow down the tears that threaten. She /knows/ he hasn't changed, but deep inside she aches to be close to him again. It's been too long and she's miserable. Utterly. "It's me."
His mouth had long since gone dry and he swallowed hard trying to dislodge the sudden lump in his throat. He was paralyzed, stuck on the spot, unable to move and gods did he just want to reach for her.
