it actually makes sense.....
think what has dev done except to talk.....
confessing to maan was inevitable..the only way to still make maan in favour was remorse act....
after the self confession whatever naintara would have done they couldnt have come out of the jail....if he wanted he could easily have stopped......
using meera's soft corner was manipulative...even though had numerous options he could have talked to maan....
reversing power of attorney is easy so the shares which naintara had taken could be easily revoked....
dev goes to hoshiarpur and doesnt find anybody while maan manages to call daarji at the wedding....
and as far as nt is concerned her behavior and maan's attitude towards nt were a gud reason for him to turn his backs on nt and that also pretending like he is a victim......
if you remember the day after wedding how dev has treated nt at the lodge where he stayed with geet...
that is the vicious dev.....
the rest was all the show to come out clean in maan's eyes and when he saw its not working but till now he was relying on nt's evil instincts to stop nt wedding but since she was not successful now he has returned...
also we saw that brij was bailed and it is clear that neither nt nor arjun got his bail.....so may be it was dev.....
just a thought that dev could be more evil than what he looks....
and as for maan it is quite evident that dev doesnt like him and they could be step b rothers so may be he hates him to core.....
just something that came to my mind....
