loki can't belive the love of his future self who fight him , just sacrifice her life for him and half of humanity . He can't belive he found love . The feeling he thought he never feel. He feel bad. The people he think of the world were dead because of his deeds.
He saw her again . A picture. The women who saw the real him. The women who show what love is.
He know what his future him do after her death. create another reality with her.
He know that he did'nt had the luck to be with her. So he cut out the picture of her from her file and tuck it into his Shirt pocket.so she would be with him.
Always......
