Don't expect any logic from the show.. 😆 The pregnancy and surrogacy comes into picture only when the CVs remember it as per their convenience.. Teni is absolutely fine while riding a bike, doing dance steps, but she faints only during important ceremonies.. Neither the family members object Shorvori dancing, nor Part-Shorvori-Jalpa object Teni dancing (they used to do it once upon a time though).
Maybe Jalpa wasn't home when Teni fainted (as per spoilers she will appear at the last moment trying to save the situation by saying Teni fainted because of dehydration), and restricting the other doctor wasn't in Parth or Shorvori's control..
Can't guess anything about whether the marriage will happen or not.. But as per spoilers, Dadaji will ask Aman to move to US with Teni and have the baby delivered there.
