Oh yeah I forgot that took that out. They 'fixed' that when Ossus was released?
I did like the HK bonus chapter. I do hope they do more of them in the future. However I think 'cloning' her and putting her on the cartel market would be easier and profitable.
I was making a reference to a line in Kotor 2 about Sion and vibroblades.
I could totally see Vaylin sleeping with a large quantity of weapons around her in case of a sneak attack.
They could always do one of those "Oh I'm not really dead" lines they gave to Darth Savik or just have her shrug off the wound entirely like they did with Arcann, Theron and the player with whatever reason.
I think they'll die in the saboteurs plot. Killing Arn would likely drive Tau insane to the point she'll get herself killed too. I don't know about Rivix, I'm not a fan of Mr 'I'm obviously not a spy'.
Best guess would be either Revan or the Exile. Personally I hope it's the Exile. I always liked her character in kotor 2 and I want to gift her with watching Scourge die in the same way he killed her.
Vaylin might be one of these 'returning characters' in whatever mess we're about to awaken with Satele Shan. So fingers crossed she at least becomes a temporary companion like Darth Marr. Then we can just bail on the chapter with her and keep the companion.
