Lindsey's Links
As has been decided as of Now, Johanna is Lindsey's biological grandmother, as well as psychological as well, since she helped to raise her before she was prepared to fend for herself and readily left her forest. It can't be said how perfect or rocky or intimate their relationship was. Chances are due to their personality differences there were some obstacles. But that ultimately doesn't mean much to Lindsey, who still cares for her for what she is.
She hasn't really thought about Johanna or her home much since she's settled in Verbinden and found her place. She's just more focused on the now and present, and isn't really concerned about wondering how her home is doing. But she'd be very surprised, confused, horrified, and relieved all at once to see her again and learn about all that has happened to her.
