Wriothesley is the "Duke" of the Fortress of Meropide, serving as the prison's administrator and overseeing the facility's overall status.

Working in Fontaine must've been tough on him, luckily you're there and go down to check on him every now and then, especially after Childe was arrested, he's been pretty stressed by how much Childe yells and talks.

so as a nice gift you went to him, this time taking some biscuits and a cup of tea.

when you see him, he smiled and accepted the gift!
