Those 2 scenes are with Jessica, you have to go back to Episode 3 and choose to not risk your relationship with Jessica.
Tried it, didn't work :/
I think he meant mine, but anyway, I got them.spoilers...
So the last 2 on page 6 are for Jessica and the first 2 on page 7 are for Skylar. And it depends if you risked your relationship with Jessica at Ep3 like Vlenebrae said. Basically, you can't get all 4 on the same run. Well, as far as I know.
