You know how quest log is always written in plural? I took that to mean "we" as in "our party", however if you choose to have that one night stand with Astarion, the PC is the only one to see his scars. Still the log reads "after spending the night with Astarion we..."?! WTF?
Maybe our PC has a backstory afterall - maybe he/she is shisophrenic or an intellect devourer? (No but really I got uncomfortable "Us" vibes from that, though it's probably just an oversight)
