Umm, Jon, the smallest size is bold; I'm not sure which one you're talking about.
First group: font size 3, regular
Second group: font size 2, bold
Third group: font size 3, bold
Which of these do you mean?

Unless you're referring to a caption under a picture instead of the quotations and the titles? There's one of those in the second group that I forgot to change to bold, so don't go by that.
