Sam takes notice of the girls mended wounds, the skin around them singed red from heat. Recognizing the marks of Caelyn's healing, Sam nods and gives his sister a thumbs up. "Good to hear. We're not out of this yet."

"You guys," he turns to the civilians who can't fight and addresses them, "Wait a moment after we go up so we can draw their attention. Then try to make a dash for the side of the ship and jump to the pier so you can get out of here. Hopefully they won't bother with non-threatening targets." Once they are coached, he charges up alongside Leaf, carrying Grepha on his shoulder.

Running onto the deck, he pivots out of the silence field just above and launches a pair of eldritch blasts at the assassins. Then he kicks off and runs up the stairs onto the above deck. Grepha takes off from his shoulder and sails at one of the spellcasters like a comet of sickly green flame, hoping for an easy target.
