tl;dr this is re-using the materials they used in her trial quest, along with 5th singularity and her character profile. tbh, kind of disappointed that we didn't get fresh new info out of TM about her, but still better than nothing. I just hope that after this, TM would insert her into the next Lostbelt storyline (because it's in Britain, it should be logical to meet her there) and maybe provide us with new voicelines that's updated (like how Musashi got another voiceline after Shimousa). She has been neglected character design-wise for far too long.
