@ FTMG. The way Jura shook his head made me think that he was acknowledging Erza and Fairy Tail's strength in a kind of nostalgic mind of  way as he considered the Erza choice was reckless, but  reminiscent of the Fairy Tail he knows when he fought a long side them remembering the Fairy Tail which would not back down from a challenge no matter the how big. He was showing joy in Erza's victory over any other emotion he felt at the time.
