i am not understanding this???

ok i am not understanding whats going around here??? after today where they all pretending to lie on the floor and play dead and after that they get up and gather around massi and let her know of her evil intentions and abha says that he got karan's help to find out what was massi and dushyant were planning.. i cant believe abha still believes that this guy at there house is karan. abha did you not hear massi saying that she killed karan so how come you believe that sidharth is karan. but i have a question will abha find out that this person at swarn bavan is not karan but sidharth aka ranchod??? i hope she finds out and goes and finds karan.........

wasn't karan in a government hospital, how did he reach in another hospital, how is he in a coma when the doctors said he will be going home soon, abha should be celebrating her pregnancy with the real karan, being romantic with her husband not her brother in law, this storyline is corrupted, i myself don't understand.
