Since the Cannaris empire was hostile territory, Andrew decided to have his date with his wives in the capital of Tampilla. Obviously, he would have to go on a date with each of his wives, but at the moment they were busy with other matters, so they decided to go for a group walk first and planned the dates for another day.
The capital of Tampilla is quiet and being new to the place they have not yet had enmities with anyone, so they could walk around without problems. This does not mean that they did not have protection.
Marie, Vala, and several Shadow agents followed them in the shadows, while Oliver and Erick accompanied them as part of the group. Normally Castor would also go, but since he wasn't present, it was just them.
