I did find a few things. Once, when I talked to Cedarstar (a few days after Echoflight's death at the moonstone where I BRUTALLY MURDERED her :3), she said "I hope Echoflight doesn't think I'm mad at her. Of course she doesn't! I gave her everything blah blah blah". Plus a few other times when characters have brought up the names of dead cats, such as Flintsong and Hawkfeather.
