Frankly...the four characters of this show need to go on a vacation..seeing they are so emotionally charged. But since that is not going to happen, two things are possible, Sam might ask for sometime..as its too soon to get engaged to Arjun, even if thought from a normal point of view.
Sam cannot say Arjun to win over Radhika and Neil's trust..its too much to expect from Arjun...why would he do that?? and why would Sam ask for such a thing?
She could ask for some time, and this would piss off Arjun for sure, and his aim will shift to Radhika, because she came in between. Then only will Arjun go after her...and then whatever happens, we will see.
Sam is herself in turmoil over Arjun, she is deeply attracted to Arjun's mysterious persona, but that does not necessarily mean, we love that person. If we date someone, is it necessary we will fall for that person only, no right...first Sam needs to be sure that she loves Arjun or is attracted to Arjun...
Arjun is not in love with anybody, but feels deeply for Nandu and her plight. He only understands darkness, loss, anger, hate and revenge. He will also chase Radhika, because she came in his way. Radhika is just a hurdle. Whether that changes to love, is what we have to see..
Neil is deeply attached to Samaira..come on, 20 years is not a joke. Till now Sam and Neil's attention were on each other, but now Sam is moving away. Neil fears losing her and understands that he is in fact in love with his bestie. But its better to lose who you love than losing your bestie..so he is doing what he does best..being the bestie. But, don't expect him not to feel any pain..He is but a human.
Radhika is annoyed of Arjun, and disliked him from the time they met. For her he is arrogant, rude, mean, angry, and now a two timer as well. She can never fall for such a guy. Even after all is sorted, she cannot fall for him, because he has made her life miserable. And, she being ethically strong, has an obligation towards Saral and her family she loves so much..so Radhika will not fall for Arjun...definitely not so soon..
