A guest from Montecito, California, sounds like it's probably someone from Caleb's family. Caleb’s biological mom lives in a fancy town in California so she is our prime suspect. Marlene has already hinted that we might meet Caleb's bio mom in Season 3, and now it seems more likely than ever.
This would also make sense given the news that Episode 4 will feature a "powerful" Haleb scene — Hanna (Ashley Benson) and Caleb's relationship is often at its most moving when they bond over their complicated family lives. As long as Caleb doesn't think about moving back to Cali for good, we're happy.
What do you think these clues mean? Let us know in the comments.
