Cecily couldn't believe that she wasn't protecting her fellow humans against the Lava Titan but from Lucian himself. Her childhood friend!
Then again, she expected it, coming from him. Even young, he was always unsympathetic, especially to the weak regardless of race. He would use anything in his hands in order to win, even if sacrificing others to achieve his goal.
Lucian was actually a cold person despite his kindness and caring attitude towards her and Rosa.
"W-we're doomed," Jules lamented when there was no end to the lava golems in sight while Lucian remained locked in combat with the Lava Titan.
One wrong move and Lucian could get severely injured, and the next target would probably be them. If that happened, they'd really be dead.
