There is nothing to agree or disagree on here, it's simply a bug and an unintended massive spoiler for the main story and its three characters that are not intended to be revealed yet.

She previously had no comment whatsoever when the party comes back to camp after the astral prism reveal, just before entering ACT III. That's what this line is intended for, however its addition entirely broke her character to the point it replaced all her other comments about other situations;

  • Recruit her for the first time? Says this line.
  • Karlach gets her engine fixed? Repeats this line.
  • Shadowheart makes her choice in the Shadowfell? Repeats this line.
  • Doom Last Light Inn? Repeats this line.
  • You leave the Shadowfell? Repeats this line.
  • Final boss in ACT II is dead? Repeats this line.
  • She becomes your love interest? Repeats this line.
  • And so on to infinity and beyond.
