Awareness seems to have the most potential if it is going to be used to gauge other people's tones/moods/body launguage in conversations. I think we will see a lot of people trying to be deceptive when speaking with the PC, and being able to see through, or even play along with, someone's lie could have interesting story repercussions. Romances, if there will be any, could be made a little more interesting by perceiving what another person is feeling, and whether it not it would, for example, be prudent to press them on their feelings or if it would make him or her uncomfortable.
I'd imagine things like Repair and Treat Injury will play somewhat minor roles in the story, such as repairing a broken console to access it or treating an injured NPC's wounds (ala the Wookie in the Shadowlands that you had the option of healing, which always succeded by default).
