Ami, if you were thinking Cordelia was going to try to have a conversation with a rock, and that she would actually feel bad about engaging said rock, you're barking up the wrong tree.

But nature puns aside, it probably wasn't the best decision. Even still, this person was threatening the wildlife here, and, by proxy, the safety of Union. That came first; she was a former Sword, and some habits never die. Let the kids talk. Calling Lucario back into the band, Cordelia stays afloat, moving to give Robin a better vantage point. If there is any further threat, she would strike, no questions asked.
