Pakhi seems to be the only string he has been holding on for so many years to deal with pain and stay alive....I guess he actually is right when he says he'll die without her... he'll probably crumble to his pain to that fire that is still lit in his brain....for Agastya to change the child him in needs to heal...the child who was wronged ...the child who is still in that room where he was burnt ....he needs proper treatment plus affection.Some observations to make from the last 2 episodes-
1-Trust the Mastermind to have the last laugh.Until now Paakhi & her cohorts Ishaan and Viraat played the game quite brilliantly however their Video trick backfired on them.
2-Paakhi knows that Agastya loved her madly hence she decided to take the advantage of his emotions by showing herself in Peril in that video however Agastya using his presence of mind made himself unconscious right before the Press Conference and reached the location albeit in a silent manner.
3- This threw a wrench in her plans and left with no option Virrat decided to use the Fire-Phobia trick to extract the confession from Agastya.
4-Paakhi did not want to use the same Phobia against Agastya but she was somehow convinced by both Ishaan and Viraat to use the same trick.Ultimately Viraat's plan proved to be a major success where Agastya was finally forced to confess all the wrong doings he did till now.
5-Viraat might have recorded the entire conversation on his mobile Phone but his time was up and Agastya's time has started by then.Just see the intense determination on his face when he said this line(don't remember the exact dialogue scene) " Tumhe Lagg Raha Hai Ki Tumne Mujhe Paakhi se Hamesha ke liye Alag kar diya hain Haan lekin Paakhi khud chahkar bhi mujhse dur nahi ho sakti & After that he said that neither any Law/God or anybody else can keep Paakhi away from Agastya Raichand.
6- Like a True Mastermind he kept his Trump Card till the last second-Yug with the help of the Smoke Bomb Agastya was able to escape the Crime scene taking Paakhi captive along with him.
7-Not only that due to the presence of Police Checkpost all over Delhi city he disguised himself as a part of the Festival Procession Band where after a through check he was able to escape that checkpost too where Paakhi was already unconscious for 12 hours in that Big Drum due to the medicine administered to her .
8-Paakhi was right in stating to Agastya that she was just a mere obsession and not love for him however like the Maya of Beyhadh he simply refuses to back down doesn't he? Yes he intensely loves her but too much of anything is bad without giving the proper time and space to grow any relationship.Not only that Agastya is also a criminal in the eyes of the law now but he might escape the same as it happens in the serials.
9-Paakhi might or might not fall in love with him but at the EOD it all depends on Agastya as to how he treats her going forward and keeping her captive in chains like he did with Paakhi's Dad is not going to sway her mind in loving him.Agastya has selective amnesia like Vansh when it comes to Paakhi-he forgets that she is his wife now and should be given the equal respect and status like any married partner which he was giving till now.
10-If Agastya really loves Paakhi then he needs to change himself for her.I would like to see a calculative and a reformed Agastya somewhat like Veer who would move heaven and earth for Paakhi but will Agastya really change for Paakhi?
Agastya is so hell bent on having Pakhi to himself is because he knows no other way to live I guess....the way he said tu nahi hogi to mere jeena ka maksad hi khtm ho jaayega....he is not just obsessed with her...she is the only thing that keeps him alive I guess...he survives just because of the fact she is close to him ... that's his messed up mechanism to live after the incident that occurred to him...he says ki wo Pakhi ka universe hai ... to be honest he has made her his centre of universe.. he'll return to ruins without her.His obsession comes from a survival instinct.
