The character of Louis is named so because his father was French. However, as a Hungarian, everyone pronounces his name with an "s" at the end, like "Lewis". Despite this, the character never corrects the mispronunciation, which he would likely notice given his background.

When Antal and Louis meet and Antal introduces himself, the movement of his mouth does not exactly align with the sound, indicating that the line was recorded afterwards.
