Well first its ITV , u can't expect logic from them .unfortunately this is the bitter truth for us...We will crib but....
we can say n demand things , if they wish, will full fil then ...but lower ur expectation n watch it then u will get it 
Sec I know n got the point but these guys messed big time so trying to do some damage control through a few epis need to see how far this will go meaning Imlie's 360 change 
third Imlie didn't open her mouth cause she is still traumatized let's cut some slack for her
she was aware that time Aryan (during a fake wedding ) , helped her, defend her , even during the wedding but Imlie was not Imlie, she was trapped with her own confusion, even now also but with wedding n the reception debacle make her see things another way then she witnessed the pain of Narmada n Arpita more closely...third She can see how Aryan was burning with this revenge 
yes if they show it gradually or in some monologue then might be but they did already the blunder with the Forced wedding n Imlie's ckt's regression after Aryan's first accident 
this should happen from his first accident or atleast cvs should have shown some flashback but maybe a certain faction
u knw some X faction can't discuss here also happen
right now it might be regressive or patriarchal or whatever but Imlie long for bond n name security which she found through this wedding yet she is confused y this wedding happen, revenge or her insecurity played by someone.
she can see her ABP is still the same then y she feels like that during the wedding then this accident, shook her ...
After Aryan at hospital , Imlie can relate as wife this with Arpita who lost her husband , Imlie now can relate how Rathore lost a son n another one is verge of destroying someting 
she is confuse yet wants to help
she has deep feelings, bonding everything for her ABP n when she notices certain changes she can't take it
she is spoiled also little thanks to Aryan who pamper her n Imlie knows she can do anything 
For that Aryan threw her those words
Imlie also wants to know then this wedding is fake for him but her ABP didn't reply
right now Cvs if not flashback then can show or give some monologue from Imlie to get the point 
now coming to the job
Aryan didn't accept her resignation so question tham jata hain uha 
but I think n wish Aryan give her a tough time as she needs to learn certain things
now coming to Imlie being bechari , well its Imlie's way, she know her tears, her helpless situation move Aryan but this time will not 
sec Imlie needs to learn as during their journey after wedding Aryan ne bola tha victim bannna bandh karo same 
third Imlie has issues n needs help, therapy in the real-world...or say moral boosting n which Aryan did n do for her.. 
Cvs will focus on Imlie's study or not , will time tell, this track (revenge) will tell us , within a couple of epis...
Hope this will help u
