Acceptation
You say hi to Tilas and tell her that because she seldom talks about herself, people don't really have the chance to know her. Thus, you hope she can tell you what she has been through.
"I didn't expect you to care about such things."
(Tilas looks at you with surprise.)

"It's not that I seldom talk about myself, but I don't remember anything that had happened before coming to Alternate Jale."
"When I awoke, I was already in Alternate Jale. I didn't know who I was or where to go. Fortunately, Sage Babama took me in. She is my lifesaver. That's why I joined this investigation, hoping to return her favor."
"It has been a while, but still nothing came back to me. That's why I seldom talk about myself."

"Although I lost my previous memories, I seem to remember deep down in my heart I am craving for more power."
"And I have been following the voice in my heart and keep walking ahead one step at a time."
"For someone who has lost her memories for so long, this is the only goal I have."
(Tilas talks about her amnesia with a blank expression, as if it were someone else's story.)
