Unsure about the fragment, but for the CGs, pg 19's can be found by following Colt and Jess' route until the red choice, where you must choose to follow Ken and Jean. 22's top middle I believe is the same as getting the top right cg, but picking "best friends" at the last choice. 22 bottom right is...I think going Takoda's/Ken's route and choosing to stay with Colt and Jess for the red choice? I'm not sure, I can just tell that it's the same cg as the next one, except Grey doesn't wear the same clothes. And the last one is just doing Takoda's route and choosing to stay with Colt and Jess on the red choice.
