Kyran found himself looking at Cyneah's sleeping face when he woke up. At first, he felt somewhat restless when he started to regain consciousness because he did not want to go through the motions of recalling True Void's departure again. But when he saw Cyneah, he was reminded of her silent presence and unconditional support throughout yesterday's ordeal. That helped him sort his thoughts and view True Void's departure more positively.
That was not to say that Kyran had little affection for True Void. Instead, he believed the latter deserved to rest after suffering for so long.
It also helped that the memories Kyran received from True Void allowed him to understand the latter's past and how it affected the situation they were currently in.
