About Terry's dialogue, I was also wondering about that.
Checking the script, the dialogue you get when Kim asks about your type is dependent on the "points" each of the guys has, based on your choices during the story.
Now I haven't had issues getting Beru- and Kim-related responses, but haven't been able to for Terry.
Checking the script file says that if your "points" for Terry are >=5 then that's how you get the Terry-related response.
But, is it possible to get 5 points for Terry while choosing to sit with Kim that night?
Chapter 1 has 2 Terry points that I can tell: (Be Straightforward) +1 and (Share with Terry) +1.
Chapter 2 doesn't seem to have any, but that's mainly a Kim/Beru chapter.
Chapter 3 technically has 3 Terry points. The first is going after Terry, you get a point for picking this one. (3 points so far)
Another point is freely given at the end of that path, regardless of whether you stay with Terry or go with him but head back to camp early. (4 points so far)
But the only other point I could see was for choosing to sit with Terry at night.
Surprisingly, there's no point to be gained or lost for stopping Terry from hurting himself with the knife, or not
And, sure, all that adds up to 5 points, but if you sit with Terry, then of course you can't sit with Kim and thus can't get the dialogue.
But, if you choose to sit with Kim instead, you will only have 4 points at that point, which isn't enough for the Terry-related dialogue.
I could see the dialogue if I just edited the Chapter 3 script file to check for >=4 Terry points, though.
Because I just couldn't see how to get the 5 points needed by default.
