i don't think ishita has still feeling for subbu.CVS r master of messing up dialogue. and is hit a never said Raman to respect shagun as his ex wife BT to respect as his children's mother.now in subbu case if ishita not forgive him it appears as she has feeling s for him BT if she forgive and talking to him normally it also looks wrong as she has no other link with subbu like Raman has through his children.
