doubts on Aankhen picture

[V.]

pls shed some light- in the ending part of Aankhen, how do Akshay and Arjun know that Sushu has shot herself and not Amitabh has killed her? Another doubt, who is the actress in the bar song with Paresh (great super actor).
Thanks.

Hey bhai, they both hear the gun shot and Amitabh comes running to them saying that I didn\'t do it, and it was she who shot herself. Gottit pinto.

one more question on Ankhen...in the climax, how do \"the sixth sense\" fellow and Arjun find about the teacher\'s brother?
