beyhadh - does Arjun know that Sanjhh loves him????

Hello, I am following Beyhadh and its a very gripping story. However, I have two questions :

1. Sanjhh is crying and making a fuss because Arjun is paying attention to Maya...because Sanjhh loves him and expects him to love her. but does he know that Sanjhh loves him? how can he know if sanjhh has not expressed her love for him? does she expect arjun to read her mind? for him, she is his best friend and that she feels the same as Arjun feels for her, a best friend only...this is silly honestly..she should be told that Arjun does not know that she loves him
2. she saw the clues in Mauritius "love treasurehunt" . however, did Arjun know that Sanjj is in Mauritius? how can she expected to feel that the clues were for her while arjun thinks that she is in Mumbai and even they talked on the phone. HE DOES NOT KNOW THAT SHE IS IN MAURITIUS, so how can he leave clues for her? and how can Sanjhh event think that they are for her while she has not told him that she is there?? this is bit confusion...
