Unchained Variant Multiclassing + Evangelist

[Tinalles]

Suppose I make a PC using the variant multiclassing -- say, a witch with the bard features -- and then enter the Evangelist prestige class. When the PC hits Evangelist level 2, I have to choose "a class she belonged to before adding the prestige class to be her aligned class".

Do I have to make a choice between witch and bard (primary and secondary), or do I get both?

You get the secondary progression regardless of what class you keep taking levels in. You also don't actually count as that class for anything, but the abilities VMC grants, so it's not a valid target for Evangelist.
