Severus followed Hermione after giving her a few moments of a head start, and he made sure she couldn't see him as he followed.
He stopped when he saw Hermione. Hermione looked like she was having a panic attack of sorts.
"It's only a nightmare," he vaguely heard Hermione whisper.
For a moment Severus stood there confused, watching his wife lean against a tree, taking deep breaths, and whispering to herself. This was a Hermione he rarely saw. She looked almost fragile and weak. She inever/i allowed herself to look fragile and weak.
"She's scared," Severus whispered his realization aloud.
