I do have to say it's amusing that makers have gone with the "keep a poker face to make people question your intentions" angle for both Abhi and Akš
In Abhi's case, they used it for the resort epis and now it has been proven it was all Goenkas ka overactive imagination and paranoia that read too much into Abhi's poker face.
And in Ak's case, I think we got a glimpse of her unvarnished reaction when she first saw whatever is in the party video....there was horror on her face as if realizing something monumental and then she ran to meet Abhimanyu....even if she had a zombie/poker face again by the time she met him in jailš, we could already see from her previous reaction that clearly she does feel something on this topic but makers want to keep her reaction a mystery for now so they have put her back in poker face mode.
Another way to look at it is that Ak is in functional mode right now ki bas kaam pura karna hai of proving Abhi's innocence so she wants to lock away all her emotions in order to get the job done....and she will process her emotions on the topic afterwardsš.....that is when any regret or apologies may come out.
Abhi got the chance to pour out his emotions today in front of her cuz he basically seized the opportunity when she miraculously showed up in front of him when he least expected š....and for once, either she was too tired to argue or maybe cuz she wanted to get to the next step of fighting his case, she let him speak out whatever he wanted toš. The fact that she didn't react to any of it now indicates that she wasn't surprised by any of what he said but she doesn't want to get into processing it right now either cuz she feels there is a bigger problem to tackle first with the caseš
Also, Pranali looked way too cute in that scene where she sees the video clips and is utterly shocked. Her face was literally 'š³' this emoji. š She has a very pretty face. š
