Who is that smiling women in the middle? Why its Lady Subhadra!
Subhadra : Daughter of Vasudeva and sister of Lord Śrī Krsna. She was not only a very dear daughter of Vasudeva, but also a very dear sister to both Krsna and Baladeva. The two brothers and sister are represented in the famous Jagannatha temple of Puri, and the temple is still visited by thousands of pilgrims daily. This temple is in remembrance of the Lord’s visit at Kuruksetra during an occasion of solar eclipse and His subsequent meeting with the residents of Vrndavana. The meeting of Radha and Krsna during this occasion is a very pathetic story, and Lord Śrī Caitanya, in the ecstasy of Rādhārāṇī, always pined for Lord Śrī Krsna at Jagannatha Puri. While Arjuna was at Dvaraka, he wanted to have Subhadra as his queen, and he expressed his desire to Lord Krsna. Śrī Krsna knew that His elder brother, Lord Baladeva, was arranging her marriage elsewhere, and since He did not dare to go against the arrangement of Baladeva, He advised Arjuna to kidnap Subhadra. So when all of them were on a pleasure trip on the Raivata Hill, Arjuna managed to kidnap Subhadra according to the plan of Śrī Krsna. Śrī Baladeva was very angry at Arjuna, and He wanted to kill him, but Lord Krsna implored His brother to excuse Arjuna. Then Subhadra was duly married with Arjuna, and Abhimanyu was born of Subhadra. At the premature death of Abhumanyu, Subhadra was very mortified, but on the birth of Pariksit she was happy and solaced. (from purport to SB 1.13.3-4)
