Thanks for the replies. đ It really does look like the forgot about him. Or even if they did bother to mention him, I guess he would be pretty big by now, and it would probably be better for Rashi to start off with looking after a small puppy. Even if they got a new puppy acting as Jugnu, in the story he should be at least 6 months older than he was the last time we saw him, and so he should be bigger.
Whatever the case, we can ignore the absence of Jugnu, but it really is weird that Jeetubhai hasn't been seen for months. I guess they don't have much for him to do in the show, so they have sent him on a perpetual business trip. I wish they would bring him back every so often like they have done in the past. Seriously, his beloved niece Gopi just became a mother - I would hope that they would bring him back soon for that, even if it just for one episode!
I would really like it if they could try to actually involve Jeetubhai in some more storylines now, rather than just Urmila. I wonder what Falguni is up to? If she is trying to swindle the Shah family for something (by getting Urmila all wrapped up around her little finger) then that could be a track to have Jeeubhai back for.
