Remember when Jeevika stood in front of Beeji when she got really angry with Manvi? Jeevika firmly said 'Now you will not say anything to Manvi'. After Beeji left, Jeevika broke down and cried, not because she thought she was wrong in defending Manvi but this was the first time she spoke harshly to Beeji. That's where her guilt was. Similarly, Jeevika does not feel guilty about saving Manvi, she feels guilty about hurting her family. That has been a characteristic trait since the beginning!
Those who want to find a problem in her will find thousand ways anyway. Before appreciating what she's actually done, people jump to 'So what's the big deal? I would have done the same'. Khud pe aati hai tab pata chalta hai...
