After regaining her memory she should have thought above 3 alive kids rather than crib abt lost 4th kid. Atleast they should have shown her with them and in any case they are treating her like mom so it would not be difficult for her to emote.
Afterall the kids have grown in 5 years and she would want to meet them. They should have been focussed too. So far as they are concerned it was their mom getting married to their chachu.
The serail has to run for so many eps so why hurry in getting SAM arrested so fast. It can be bit slowpaced.
What say..
