It's not likely Cole's dialogue tree. Checked the scripts there. The issue is with the initial "on enter" setup within bos_orion2. The workaround of quit the game, reload with autosave seems to work.
I did some digging and also found a mislabeled script "prefadez" in the initial dialogue tree. I'll give that a test as well as seeing if I can extract the utc file for "Sera Degana" and maybe tinker with the stats - the portrait id seems to be wrong on my copy, and I'll probably put in a "min 1 hp" clause because dying during a flashback scene throws off the immersion.
