I have noticed it forever now that Angad/Zeb answers his own questions. I does strike a little odd. Example;
1. The time Angad followed Kripa into the outhouse to ask what Prithvi was doing there, he said something like, "Kyun main yahan nahi aa sakta?? Then he himself answered it, "Oh, kyunki main tumhara BF nahin hun isliye"
2. Then in the lipstick sindoor scene, he asked Kripa what is Prithvi to her? When she didnt answer, he himself said, "main batata hun, Prithvi tumhara kuch nahin lagta"
3. Now what reminded me of all this, the dialogue b/w Z-M yesterday, "Main janta hun tum yahan meri saath kis liye ho? Then he actually said, "Tum meri saath isliyee ho, bcozz..blah..blah...blah..blah.... "
There are numerous incidents like in the outhouse fire scene, when they had their first fall out when he asks and then answers his own questions.
I guess he never heard of a thing called "Wait Time". That is the time U give the other person to answer Ur question, its anywhere between 4-- 10 seconds. I find that very amusing. Maybe he loves to ask Rhetorical questions..
