It’s not really surprising that Fate/Apocrypha is still introducing things in its second episode. With 14 (15) servants and, presumably (?) an equal number of masters to try to show off before things really get going, I wouldn’t be surprised if episode three follows suit – nonetheless, this episode did a decent job introducing lots of new characters, as well as giving us a taste of the kind of action we can expect going forward.
We see a little more of Ruler to begin with before rejoining the two factions who take turns in introducing themselves. The Black team do a full (and quite convenient) set of introductions led by their overly bubbly Rider.
