Sorry this is so short but it just felt like a natural divide in the story before the next chapter.
...
Lexa had felt Clarke's pity towards her as she had spoken about Costia and she resented it. It was one of the reasons why she never let her true feelings show for she hated pity. Pity intensified emotions, made them harder to keep under control. Not that her people were quick to give out pity to each other. She had immediately hardened under Clarke's understanding gaze and had gone on to instill her belief of love being weakness. Her confession just seemed to make Clarke pity her even more which irritated Lexa. She could not afford to have someone as soft as Clarke beside her in battle. She would have to teach the other leader the importance of emotional detachment.
When it had come time to celebrate their truce Lexa had chosen to drink with Clarke. She somehow took pleasure in undermining the girl's mother who seemed to think that she was in charge. Lexa had decided from the moment that Clarke had thrust the knife into her lover that she was the true leader of the Sky People. It had taken great strength and showed Lexa that Clarke had the potential for greatness if only she were willing to desensitise herself.
At the realisation that Gustus had been poisoned Lexa had become conflicted. The alliance with the Sky People was their only hope for the Grounders trapped in the Mountain but an attempt on her life was not something that could be ignored. Her fear at the thought of losing her protector heightened her fury and she had turned on Clarke. She could sense by the shock in her eyes that she was innocent but as their leader it was she that Lexa blamed. Having just recently opened up to Clarke she had taken the betrayal personally, something that she had been trained not to do yet it was as if her training was slowly seeping from her brain as she stood eye to eye with Clarke. Even when the evidence was found Lexa still hesitated. She had grown to grudgingly accept the Sky People, this was their only chance of a truce. There would be no going back. Lexa had to side with her people however and the attempted murder of the Commander was punishable by death.
She had notice that Clarke was one of the few of her people that did not come out to witness the punishment of the one named Raven. It showed poor leadership skills Lexa observed. A leader should be with her people. Perhaps it was too much for the young girl to face so soon after the death of the boy. If that was the case then it was best that their alliance was over Lexa had concluded. She had no patience for the weak minded. Once again though she was infuriated by Clarke's obvious fragility. Why did it bother her so much how Clarke chose to live? Not for the first time when questioning herself about Clarke, Lexa could not come up with an answer.
Clarke had slightly redeemed herself in Lexa's eyes when she discovered what had truly happened with the poisoning incident . Lexa had been taken aback as Clarke took a swig from the bottle. It took true conviction for the girl to risk her life based on a hunch. Admiration had flooded through her. What was it with this girl? How could she be so weak one minute yet show great courage the next? She was clearly a complex character which intrigued Lexa. She prided herself on her ability to hide her feelings while being able to read others so well but Clarke was the one person that she struggled to figure out.
With the revelation that Gustus had been the guilty party Lexa could once more feel Clarke's pity towards her. She forced herself not to look at her. It would only make what was to come more difficult. In some ways now the two leaders had something in common - having both been forced to kill ones that they cared for, for the good of their people.
After she had ended the life of her most trusted guard her eyes had sought Clarke's and she had allowed herself to wallow in Clarke's intense stare so full of warmth and sincerity for just a moment before turning and walking away.
