Drune had stayed up for a little bit for the captain to return, hoping to use them as a means to get off the ship. There was a small hope this could end peacefully, but as the night crept up, and the appearance of that person not coming back becoming abundantly clear, it seemed apparent that she was not going to return. Perhaps that sort of pity caused him not to attack them in the middle of the night like he planned.
Getting sentimental in your old age, Drune.Still, as the morning sun began to rise, and the truth of the entire situation came crashing down on him about their captain, He began to rise, gathering his gear and equipment, checking them all to ensure they were in working order. It wasn't the best he could possibly be equipped for a assault on a ship, but with only two people, hopefully he could catch them off guard and make this as painless as possible.
If they wanted to wait for their captain, he'd gladly make sure they could do just that.
