Scarlet and Sean (Sid's friend) fought side by side as they retreated with the other members of Twilight Rain toward their Inner City, where their Leaders were currently at.
The two only dealt non-lethal injuries to their opponents, using daggers coated with powerful paralyzing agents that would make their foes unable to move for a few minutes.
Both of them had to make it look like they were seriously trying their best to kill their enemies while making sure that none of them died.
At the end of the day, they were the Half-Elf's double agents, and killing the Rankers from the Kingdom of Gweliven wouldn't do them any good.
All the manpower of Twilight Rain had been recalled from their missions in order to reinforce the Main Headquarters.
The pro of this strategy was that they were able to resist the full might of the Kingdom of Gweliven.
