Mallika: Well Mallika was this confident, high class, beautiful young lady, who was really proud of who she was. She loved Armaan a lot, and has been waiting ever since the serial has started to tie the knot with his Dream guy Armaan. Since she was so high class, beautiful and confident, she didn't understand a middle class, ugly, girl. And she was never able to undersand that why Armaan liked her and favoured her so much. Mallika was supposed to be a negative character, and she was a mouthful and was lots of time rude to Jassi. But she was not those typical Ekta Kapoor Vamps. She also believed in a Woman's pride and even gave the courage to Bindya, when she was going through a rough phase. She also really like Gulomohur, and never in her dreams she wanted to do anything bad for it, she wanted the Company to move forward. Being Armaan's girlfriend she was alwys very suspicious of Armaan's where-beings.
About Armaan and Mallika's relationship: Mallika always tried her best to maintain the relationship, but Armaan was never seriously involved, because of the facts that she was to suspicious of him, didn't help him much professionally and personally, she was Aryan's sister, and because she was a bit arrogant, and wasn't much fun-loving and didn't get along that well with Raj. But still he did liked her, and did share some good moments wth her, when they use to discuss their old college times.
Now my debate is, if Jassi didn't come in Armaan's life was it possible that Armaan and Mallika got together. My answer for this would be a total yes. Because Jassi was everything that Armaan wanted minus the looks, For Jassi Gulmohur was her heart and soul, she kept all armaan's secrets, she was fun-loving and got along with Raj also, she was also very philosophical and use to teach him lots of things through her Bebe, she was simple and not to complicated to understand. I don't know if Armaan and Mallika could've fell in love if Jassi haven't come, but she did minus both of their chances to come together, because there was no one like jassi, she had everything that Armaan sub-conciously wanted in a life partner.
So what do you guys think?
