The Could and the should

The could be ...

A) bijoy knows why Elena has come and who sent her
B) that dev the duffer will get all OTT senti and tell mata Shri who will now use soha to manipulate him
C) GKB and Vicky will try to distance soha and sona -- they know dev will not give her up so maybe harm soha or sona or both?

The should be ...

A) dev standing up for his wife AnD daughter - both
B) Soha and GOLU standing up for him and Elena
C) sona surprised at the changed dev - Stronger and willing to face the truth

A strong ending and a happy one --- would be great
