Hi, can someone help me out and give me a reminder on how the Petrova bloodline continued?
So the last Petrova doppelganger we saw was Elena, but how did this happen?
Katherine had Nadia, so does that mean that Nadia had a baby of her own and that's how the bloodline continued to grow; leading Elena to become a doppelganger?
Anyway overall, how did Elena become Katherine's doppelganger?
Thanks.
