* Season 5 had... problems, to say the least, but the final scene of the finale is a touching nod to [[Franchise/StarTrek one of Gene Roddenberry's better known works.]]
* Liam's anonymous blood donation to Sandoval. It had a chance of revealing who he was, and/or ''what'' he was. Liam also knows full well that Sandoval is, to put it mildly, not on the side of angels. However, add it to how little he acknowledges [=Ha'Gel=] unless ''absolutely'' necessary. Despite everything, Liam's donation says that he acknowledges Sandoval as his father, and loves him, despite the messy situation.
