No need to apologize, I thank you a lot for reply.
Anyway, I tried to reach Kierce ending again now, and it seems I just wasn't spamming hangouts enough before - it indeed is there - and even though I have to admit that I did not like his character as much as others before, that changed now :). So that was mistake on my part, and I'm sorry for that.
Thanks a lot again, good luck with everything, and take your time (as I said - enjoyed this game a lot so far).
