Rudra surrendered without struggle infront of the hostile elves , however if he wanted to fight them he could have easily killed every single one of the elves pointing an arrow at him before they could even say ' Help '
However since he was at his in-laws at the moment , he did not want to behave in a barbaric unruly manner and hoped to resolve this misunderstanding peacefully.
It was only when Legolas arrived at the scene and instantly recognised Rudra that he ordered the men to stand down and de-escalated the situation , otherwise the other elves were bent on putting Rudra under restraints.
Legolas said " Put your damn arrows down men , that man is the KING of Avalon and the fiance of princess Ruby , moreover he is a warrior that can whoop your as**** before you could even blink your eyes , so show some respect ".
Rudra looked at Legolas and grinned as he hugged his old buddy tightly , Rudra said " Good to see you buddy ".
