Garcia was just talking to Derek about how thankful she was that you always looked out for her, including getting her a coffee that morning. You always did things like that. Sure, it might've took Garcia a little longer than the rest of the team to notice your feelings for her, but that didn't mean she wasn't a good member of the team. When she finally pieced together your affections (after being teased by the team) she felt dumb. She liked you back, of course. She had since you met her, immediately blushing red and complimenting her earrings. Garcia wasn't one to let things control her, but she didn't want to get hurt, so she simply buried her feelings. Well, until she figured it out.
