Final answer:
The question about who Alex falls in love with at the hospital cannot be answered as the provided texts do not contain enough information regarding this specific event or character.
Step-by-step explanation:
The provided excerpts do not explicitly state who Alex reunites with and falls in love with at the hospital. Information from these texts point towards various settings and characters, but there is no clear link to a central narrative or storyline that would indicate a romantic reunion for a character named Alex. It seems that the student's question pertains to a specific story that is not fully represented in the excerpts given. Without additional context or information about the specific work of fiction (or a non-fiction narrative) being referenced, it is not possible to accurately determine the character Alex's romantic interests or storyline.
