Eric

Eric is Zoe's longstanding crush, and eventually ends up married to her. It should be noted that Eric had a crush on Zoe as well, and Liana notes that neither of them were aware of the other's feelings. Eric's number is an eight, as he is described as a perpetually happy person.

Book One
Eric vouched for Liana when Phineas, a water treatment worker, demanded that she sat up front.

Eric stopped Zoe from lunging at Liana, who lied to them when she was hiding under a bridge in the greenery.

Eric was with Zoe in the Medica when Liana went to save her.
