The strange atmosphere was broken when one party decided to strike first.
It wasn't the pursuers that had the advantage of numbers nor the sword wielder who looked strong but it was Celty who decided to move first.
Fuuu!
A ball of fire was hurled out at the sword wielder and Celty too clenched his teeth and dashed to him as well. If he had any other options left, he wouldn't risk such a reckless move but options were a luxury he didn't have at the moment.
If he delayed his actions any further, once the poison spread throughout his body, he would die without a proper burial. Rather than waiting for his end, might as well risk the last bit with his life.
Had he succeeded?
The reason he chose to go after the sword wielder was to increase the "what if" chances.
Celty was quite familiar with the pursuers on his tail, if he wasn't poisoned or wounded, they were no match for him but to confront them with his current condition would kill him instead.
