its a big indication, of AR endin. cuz lke ridz had made armaan promise and Armaan had even sed he will, bt he neva took it frm his heart, he always lke 2 gd to send a girl 4 him n etc.., bt deep inside his heart, he still wanted ridz. bt shilpa made him realise sum things. gettin rid of her memories is extremelly significate as it shows how he is tryin so hard to actually forget her, he is actually makin an attempt. yh 2day's epi showed how he misses her n still loves her, bt d way he rips all d memories, shows what he actually wnts to do to all of their momories and his love for her. this is d 1st step shilpa has taken in order to help armaan, yh it caused him sum pain, bt it ws 4 gd cause.
