Hi! Apologies on my lack of activity. Internet is down since the 4th, and the company says they'll send a technician to deal with the issue by the 9th at latest, though I know this company is famous for slacking. -_- To top things off I had wisdom teeth removal surgery on the 4th also, so I've been focusing on getting better. 

What I can say is that I don't really see why Charlie would show up in Lanie's life, or why she would appear in the current throwback episode since her and Maddy wouldn't really be friends.
