With the training day coming to a close, Zeph just wanted to get the daily debriefings done and out of the way so he could spend some quality time with his family and Rena before he had to depart for Central for a few days, and he was sure that Candi wanted to spend every last second she could with Justin before the Quantum Wave Enchantress left for its next voyage.
Of course, he would sneakily woosh to their side at night to give them all a little affection and what they needed, but that wasn't the same as getting to spend any real time with them. It was more wham bam, "That was great do you need a receipt," lovemaking for the sake of not letting them go without at least one daily meal than anything else.
