Do we want:
1. Manyasa to be the main lead? YESss
2. Less or nothing of the other combinations? The LATTER, (most) preferably
3. Manish to get a chance to develop various characters? YES, YES
4. Thapki to be happy again? OF COURSE
Conclusion: then let's tread with CAUTION in our observations about Thahaan/Thayaan/Aryanki, for Colours may well get fed up with all shouts from the field (even if they're not listening distinctly) and pull off TPK instantly.
They are not fan-bound, they are not Manzee-diwanzees, they are not stuck with this one serial. 'Off with TPK's head' will be their reaction, for new serials are already knocking at their door.
But then, dear friends, Manyasa will be LOST to us for who knows how long, if not forever...
So let us, please, give ourselves - or at least those who are still watching - the chance to enjoy our fav jodi for as long as they are there. As Thahaan, Thayan, Aryanki (even in Arni confrontations, for they're after all Manyasa). We shall suffer BDs in the bargain, but we shall still have our RO (real ones) also - something the non-watchers will miss out anyway...
YES, FOR SURE: If they pull out, we pull out - and the plug will be pulled out of TPK then. Simple
