Alexander will walk straight to the temple to pay his respects to Claire and pray to Theos, thanking Him for his safe return to New Wickersham. "It's good to see you again, milady. How have things been at the temple?" Afterwards, he will meet with Frederick, heartily embracing him: "Thank you for returning the children to safety, my friend! How have you been?"
After Milton, Frederick and Alexander are reunited, I suggest we go see lord Wickersham together and report.
