alia bhatt in udta punjab

i haven't seen the whole movie but my brother had made me watch the sequence where alia's character meets shahid's,I watched it again today and I am in as awe of her acting as I was then.Her breakdown was so great,be it the scene where she is walking away after tommy suggests suicide or when she tells him that good days will indeed come(sth like this).Absolutely great,sensational crying.

I am not sure if she slayed the bihari accent though,to my non-bihari years she was decent.
