When I heard we were getting a new use of the Siege seeker mold as Nacelle I was ecstatic, since I adore that seeker mold, barnone. However, there was controversy about this as Nacelle is typically a red, white and blue Thrust. I submit that in this particular release, the Siege tetra jet mold actually matches better.
