In amongst all the Olicity drama this week, there was some heartfelt mother/daughter bonding time between Donna and Felicity Smoak. While some of it verged on going overboard with the melodrama more typically associated with The CW's non-superhero shows - "...you find yourselves in each other..." - it did bring up the topic of Felicity's father as well. Donna talks about him going missing, never paying child support, and how Oliver is nothing like him. The fact that we still don't know who Felicity's father in the fourth season of the show can't be a coincidence, mostly because TV teaches us these things never are. One of the popular theories out there is that Felicity's father is actually Damien Darhk. It would be a big twist, and a shocking moment for Felicity, but at the same time you can imagine him being the kind of guy Donna would go for. Could it really be him? If not, who? Also worth mentioning on the topic of Felicity's parents, going by the end of the episode, is Mama Smoak and Papa Lance really going to be a thing? Does this mean she'll be hanging around a while longer this year?
