Personality
Lancer values a hero's pride and refuses to interfere in Saber's duel with Xia, instead stepping aside to observe. He speaks with a playful edge, but is perceptive enough to recognize unusual restraint in another fighter's technique. 18
His patience deteriorates under pressure. Trapped in Eternal Throne's desert, he becomes increasingly frustrated by the heat, mana drain, and isolation, exposing himself to Xia's guards when he calls out in anger. 31 He is also described as arrogant and prideful, reacting violently when Xia calls him a “stray dog.” 40

Eternal Throne
After Xia activates the Eternal Throne Reality Marble, Lancer enters its desert region. The barrier's sunlight suppresses his magical detection, drains his mana at three times its normal rate, and leaves him exhausted and impatient. 31
When Lancer calls out for Xia, five of Xia's golden-coated guards ambush him, piercing his throat and four vital organs before beheading him. A larger force of Xia's guards emerges from beneath the sand after his disappearance. 31
Emiya Residence Assault
In a later confrontation, Lancer attacks Xia and Shirou in the Emiya Residence warehouse. He impales Shirou and seeks to kill him again before targeting Xia, but Xia temporarily catches him in Crucifix Stone Prison. Lancer breaks free and continues the pursuit. 40
