she mightt ..

i think if arti did tell palak that arpitas coming to her party she thought about it and said it because at this point she cant be stupid to make any wrong choices . i think shes going to either play some clip of arpita and say to palak that so what if you mom cant be here but all her memories can and also say to her your mum wanted you to be happy on your birthday so when you dont celebrate and be happy your mum gets upset and arti may also say am not here to take your mums place am just trying to be your friend or something along them lines. atleast thats what i think

or she an take the crazy choice and dress like arpita and have everyone hating her :/
