I found that out of character for her as well. Been through that scene a time or two in the same playthrough since that area was so buggy until the last patch. Both times we let her take the lead cause why in the world wouldn't you? We had no intention to die by her fury right there and then. We did end up trying both the play along and truth options though. Not quite sure why she needed the guidance all of a sudden, maybe they just need to have her signal more uncertainty before the encounter to make it feel natural.
