You nod and tell Samus that you noticed his weave was extremely complex and actually reminded you of your mentor and friend, a man called Eamon Flannigan. That he lasted so long as he did is testament to his skill.
When you and the others start moving into the base, you pick up a nearby HF sword, to replace the heat knife you used, and swing it around a little to get a feel for the balance before taking a sheath. You strap it to your belt and sheath the machete. You are still not happy with the length of it, but it is better than the knife. As you sheath it, Roland steps up return the blaster. You nod and reload it, telling him you might give it to him in the next fight as well.
