Grissom was trying to catch up with Sara before she got to her car. He had the perfect excuse to spend more time with her, even if it was only for a minute or two and had good chance to see her gap-tooth smile he loved so much. If he found the courage, he would even ask her to get breakfast with him. Because he wanted to talk to her.
When he caught up with her near her car, he couldn't find the words, so he just looked at her and said : "I… You… You forgot your keys…"
