Laz's internal alarm was rather reliable. It usually woke him up at dawn every morning without fail and this morning proved to be no different. What was different was that Laz's memories of the previous night were very vague after he got done helping Abraham.
As such, when he woke up, he found that there was an arm laying against his chest, surprising him. More than that, when he tried to move his body a little, he found out that there was also a leg that had intertwined with his, causing him to be locked up and unable to move without first moving the leg.
Feeling a soft, warm burst of air hit his face, Laz turned his head and noticed that Julia was in bed with him. Knowing this, he quickly figured out that they must had passed out after assisting Abraham. As such, Julia ended up crawling into bed with him and using him as her personal body pillow which she was hugging tightly.
