Yes.............At last kaajjal gave some clue that she lost her memory. On 2 days episode kaajjal said...that she doesn't know him.Dev tries to tell her everything that happend in between them 2...And again kaajjal faithed!!!!i think dev gets to know about kaajjal's memory lost 2row.
I really found it strange that Dev doesn't notice that kaajjal doesn't remember his love ...i mean cm on she said it twice.
