Honestly, the whole 'resting' thing for coffee was unknown to me before now, I don't think it's particularly common knowledge. Having the beans already roasted before grinding is the earliest in the process that I generally participate. So even if some of you are criticizing Jeph, it's hard for me to do the same.
Regarding non-coffee speculation, I worry for Tai. She's a bit too naive and inexperienced to grasp on an emotional level that Dora is simply unavailable in the larger sense. To recap how this all started off, Dora fell in love with Marten before Marten was even aware of the possibility she might be interested. And she pursued him, in the end, because she wanted to be with him more than she was insecure about the situation. I really respect that. But we know from the comic that love isn't always enough.
I like Tai as a character. She's unique among the cast, she's very realistic (IMO), and if she's going to be hurt, I'll empathize with her very strongly. But her chances here don't seem good. The only thing that might trump my expectation is Dora herself. Both being more receptive to being pursued, and/or having a greater attraction to women might be the dividing line between heartbreak for Tai and a truly wonderful relationship.
As always, the ball is in Jeph's court.
