I have a feeling this is going to be the case. He's hired fake parents or something. There were little hints of this thru the episodes from 15th may- 21st may.
i don't remember all but:
1. pj refusing to take chandini to canada and then giving a reason and looking at his "father" to signal him to agree
2. "father" and son looking at gifts they received during roka
3. "father" coming to tell lalaji that pj wants to go out somewhere with chandini
4. pj comes back from chandini's house after finding out that she's out of town. he's angry. the whole scene with him and his "parents." they are acting so suspiciously.
i'll add more if i see it.
what do you guys think?
