Lux had come to the conclusion that Shyvana did not particularity like her. She cannot claim that she had a solid understanding of the half-dragon's personality, or thoughts, but nevertheless based upon her actions in the past twenty minutes she is certain in her conclusion. Thrice Shyvana has turned away and let the enemy fall upon her. Thrice, Shyvana has left Lux for dead. And thrice, Lux had died a preventable death. She had to bite her tongue to keep from screaming.
Of course Lux was angered. To lose a member of the team was to be at a disadvantage. She didn't understand why someone would continuously put themselves at a disadvantage. She had half the mind to throw a rock at the stupid halfling's skull but restrained herself. Do not let emotion control you, she reminded herself, calmly, coolly, assess the situation and take the best route. And it seemed that the best solution was to ignore Shyvana. So she set about doing that.
The fourth time she dies, she respawns to the sight of Shyvana all bit breathing fire in Jarvan's face. Shyvana stomps off, flames waking in her footsteps. Jarvan shoots her an apologetic look as if he were trying to make amends. Lux didn't need pity. Pity didn't win battles. She took a deep breath. Do not let emotion control you. Shyvana let her heart rule her, she drew her power from anger and rage but such things were unpredictable. Lux followed logic, strategy, absolute things that never betrayed her.
