Lucas felt Jen's body shiver and he pulled her closer to him in an attempt to comfort her. He did not think that his innocent question would turn the atmosphere to become so emotional in the first place so he could not help but feel a bit guilty about it.
He heard Jen sniffle and he placed his hand on her hair and gently patted her head to comfort her as if to tell her it's okay to cry. Jen didn't want to cry but the memory of her grandfather really stimulated the grief she had buried a long time ago.
She had felt her eyes and nose start to sting as she talked about the accident so now she was just trying to get her emotions under control.
Thankfully, she was able to settle her emotions and was back to normal soon enough. Lucas decided not to probe anymore as that would definitely ruin their current mood so he chose to keep quiet about the topic and decided that it would be something that they discussed at a later date.
