[Western Crossover] Can a Deceiver's Love Confession Be Trusted?

Bruce's eyes widened slightly. Carter Heimlich had returned. Carter and Bruce had been childhood friends. When Bruce was eight, Carter disappeared. That same year, Bruce lost his parents. Now Carter had returned, and a mysterious person had appeared. That person called himself the Trickster. The Trickster took on different identities and made his mark on the world stage. In front of the Joker, he was a psychiatrist with a toy gun in hand: [Want to see who's crazier, Mr. Joker?] In front of Iron Man, he was an AI creation that had gained self-awareness: [No one understands better than I do how you surpass your time.] In front of Superman, he was a traveler through time: [I know what it's like to feel out of place in the world, just as I know you.] The Trickster appeared before everyone under a different identity. There was only one person before whom he had just one identity: "What if I told you I've been in love with you for twenty years? Would you believe me?"
