Final answer:
The question about who watched Albert and Mercedes leave the hotel cannot be answered accurately without additional context as the provided text passages do not contain relevant information.
Step-by-step explanation:
The text passages provided do not clearly state who watched Albert and Mercedes leave the hotel. However, by the context given, it seems like these passages are extracted from different novels or literary works, which require reading the full context or the book to determine the correct answer.
Without specific information about Albert and Mercedes or a scene involving them leaving a hotel, it isn't possible to provide an accurate answer to this question.
In the passage provided, it is not explicitly mentioned who watched Albert and Mercedes leave the hotel. Therefore, we cannot determine the specific individuals who witnessed their departure.
Without more context, I can't pinpoint the specific reference to Albert and Mercedes leaving a hotel and who might have watched them. If this is from a particular story, book, movie, or show, providing additional details or the source material could help me give you a more accurate answer.
