Season 1 regulars- who's coming back?

Season 2 of this show has done away with much of the staff at ATU and PM from Season 1. But since this show is based on one known for surprise comebacks of missing cast members, we may expect a dramatic re-entry. Who's coming back?

1. Nikita Rai (Nina Myers): Mandira Bedi, who played this role, said she won't be part of the second season, so there isn't much of a chance of her coming back.
   
2. Tejpal Singh Sandhu (Tony Almeida #1): There's a Tony Almeida #2 in the ATU, Vedant Acharya. Given how often the original Tony is believed to have changed sides or operated outside the law, there's a chance that Tej may make a rather villainous return.
3. Mahinder Gill (George Mason): This season has little influence of S2 of the original, in which he doesn't last long, so there may not be much for him to do here.
4. Divya Singhania (very loosely based on Nicole Palmer): Her re-entry will be the biggest surprise. Maybe mother saves her?
5. Saxena (Teddy Hanlin): That grumpy agent who had a problem with Jai and sabotaged his mission- maybe he's a traitor with bigger designs?

With pieces from OR:Season 2 and OR:Season 4 mixed into this season otherwise based on OR:Season 3, and these cast changes, the show may be harder to predict than in its first season.

Really...!!!

True...Nikita/Nina/Mandira may not come back as they changed the story there...
in fact I 'm not counting on comebacks much as some of the key characters are yet to enter ...unless Saunders becomes Almeida #1 or Mason 😆

Hi, As u rightly pointed out, this season is mainly based on the original season 3; with many sub-plot changes.kiran's track seems like Kim bauer's track frm original season2.
