Honestly speaking, they all have a right to move on from what has happened and if theyre keeping this 'party' or whatever in order to cheer up each others mood then its okay! idk what is so wrong with it. Life cant just stop. and regarding usman's accident/coma track...well for all you know aliya might get injured while saving Usman. or maybe not. will only find out when you watch the episode so be patient!
