He & Sudha were last seen @ godh bharai. If they bring him back and show the Suday romance once again, in parallel w/ Jyotir, I'd be thrilled. But if they are going to be back just so that Sudha can be CM's naukrani to do for Pankaj things that Neelam won't do, like get him breakfast or bandage his bleeding finger, or get yelled @ by CM for talking to Jyoti, then I don't want Sudha back. Similarly, if the only reason for Uday to be back would be to be a shoulder for Pankaj to cry on, I don't want him back either.
One thing I wish to see - that whenever Neelam is fully exposed, Bhairavi is exposed with her, and kicked out of the house: let CM then go whereever she likes - Banaras, Jaipur, Kota, Mumbai... I'd also like Pankaj & Neelam to leave as well - be it together or separately.
After that, I'd like to see a return of Uday, Sudha & Pratik, and see a few episodes of Suday's romances. I'd also like Sudha & Gayatri to organize Pratik's wedding, and Sudha to be given the keys by Gayatri (which were once given to Jyoti). At the wedding, have Kabir, Jyoti, and family friends of the Vashists & the dulhan all attend, but leave out Minal, Kesav-ji, Neelam's family and all the negative elements out of it - Pankaj, Deepu, Minal, Poonam, Brij, Neelam, Padma, Sushma.. Let that wedding be a highlight of Sudha's capabilities - make her the star of this event, other than Pratik & his dulhan.
