Not quite, actually. He did sort of show up then, but it was when Alexei was about to kill Johana because she was trying to kill Katalin for killing Ilse, and Lancer picked her up and carried her off. He saw Alexei and his Saber approaching, and knew that Johana had gotten herself in a bit too much trouble.
I'll save time in disappointing you and say that the chances of me writing fanfiction at any point in the future range from slim to none. I've got other things to work on, and even MPII itself is far more than what it started out as. I originally wanted to write something fun and enjoyable as an ongoing side-story after MPII, but I might not even end up doing that, at least not immediately, and certainly not as a full-time project.
Instead, I have a number of potential novel projects to choose between; and Cool Winds needs editing and rewriting, too...
