OK, we do all know how GUL's leads come together after a long journey and they would have come together anyways some zillion times inbetween without the words but in action. Also situations play a very imp role and how we see it.
Keeping GUL aside if we see this from a story perspective, I guess here we should give a 19 year old some time to process. I mean how many at this age has that capability to understand everything and assume everything right????? Maybe just 2%. So lets give that benefit of doubt to Imli for few episodes atleast or till we blatantly see that she has indeed misunderstood her ABP.
I will circle back to the dream as that was very significant for both Aryan and Imli. Aryan saw AKT taking one of his precious family member and he wanted to stop but he could not move. So there is fear again of losing someone and the thought that he cant STOP or is unable to stop. We know Aryan is not a person to force anyone, specially Imli. Plus he has said this many times that this is just his game of revenge and no one is involved. So i will stick by this attribute of his unless i am proven wrong. Now it has to be seen that when does he accept that he loves Imli consciously and when will be realize that she is more IMP than this revenge. 
Plus this dude gives very mixed or rather no signals!! If he can say we are nor friends Imli, why cant Imli say that back??? Why does it hurt him??? He also needs to accept otherwise he is going to act like an Idiot which is going to confuse her more until she realizes that all this is an act, a safety net for him.
Coming to Imli, we are expecting too much from her at this point. She has just realized that her ABP is very very imp for her. She has just accepted out loud that she cares and she trusts ABP totally and this cant be shaken. So i am for now going to trust IMli in this new found feelings of hers. Secondly, she still has to process so many things!!! She has not been given time at all and in this case a person can be very much reactive. Once she get that moment to think then she can connect the dots or find missing pieces and seek the answers. She definitely is not going to misunderstand Aryan for herself. She is just wondering that revenge is his goal and it is so imp for him - why? Bec her nature is forgiving and she will ofcourse do her best to talk ASR out of this - for ASR and for herself eventually. In the dream, her two statements to ASR is very significant - he is not alone, and she will save him from himself. So this fight is to save Aryan from ASR. 
I am not going to bother about when and how this marriage comes to play for now. Its imp to see how Imli understands the situation and then what is her next step.
About AKT - no words as he is delusional as he thinks he is GOD!! He is going to get the ultimate surprise of his life!!
