One-night stand is not new for t and d. remember banegi apani baat? Even in that time they have shown one night stand between karna and nikita (i hope i am right with name) and yes she got pregnant and became single mother to a baby girl.
After watching yesterday's episode I was thinking its good chance for t and d to go back to BLF track......how?
Create misunderstanding between a-j separate them (t and d's favorite)
Now still gulmahor/kohinoor is still on jassi's name she has to go back to gulmahor for few months.... we can have raj pari mandi back......
Armaan try's to go back to malika but he finds out he still's love jassi so back out.......
New character which purab phoned last episode will come to take jassi away (same as Michel character)
Armaan reads jassi's diary...
And finally malika gives up and clear out all this mess........
So simple but you damn t and D
