The moment that Nushi defeated Time, Calabria underwent a dramatic change.
[View of Mex and Calabro, Moments Before Time's Defeat]
"You have taken everything from me!" Calabro screamed as he was somehow expertly able to weave through the tower's traps to chase Mex.
"I have done nothing of the sort! You have done this all to yourself! Whatever is wrong with you was wrong long before you met me!" Mex yelled down as he dodged spikes that were shooting up from the platform he was running across.
Time was forcing Calabro into an almost trance-like psychosis that was distorting reality as the Manticore saw it. This was causing him to see Mex as a monster while being assaulted by auditory hallucinations telling him that Mex was the cause for every problem in his life.
Because Time's influence was so strong, Calabro could no longer tell right from wrong or enemy from friend. Mex had no clue of any of this, nor did any of the few that knew him.
