As I mentioned, EA is a bit awkward. He doesn't have that urge to help a woman in distress. He might have done it because he was heading towards that direction or for whatever reason. Something to his own agenda. Not because he really wanted to make sure she got home safe.
I don't think it's fact she ran away. It's hope. Because then I know she is a fighter and she is alive.
I just keep going back to the drinking and adderall. Simply because I personally know how it feels. He most likely took the adderall to combat the drunk state. Bartenders do this with cocaine and speed so they aren't falling over the bar every night.. But if you take too much adderall you will feel this euphoric rush of you can do anything. Then you crash HARD. It's very unpleasant.
