Yeah, Faith 2.0 definitely feels unnecessary. There's only 3 eps left in the season, so it seems pretty late to be introducing a new character. But I guess they're trying to push the story forward of building up the ranks of the good guys for the big showdown with the Royals? (A week or two ago they teased Capt Renard hyping up the police force against an attack, and they didn't show that scene when Viktor was in town)
