A smile is not banter, but it is better than many of the alternatives. Porthos can take a partial victory when he is offered one - at least, in one such instance. He follows after his friend, and smiles as the wave of heat that engulfs him as he steps through the door. He's glad he wasn't in full Musketeer attire, on account of the warmth of the weather in the Nexus, it means he doesn't have to take off his pauldron and jacket and fear losing them.

He looks around and indeed, everyone here seems to be wearing very little. That puts his rakish smile back on his face, and he grins over at his friend. "This is a gem." This door he's found, this place he's found. Like the door to the Caribbean, but without the danger. Sometimes, even Porthos welcomes a situation where he might not have to use his sword.
