Oh, watching this episode now when there is almost a month to season 5 of Stargate Atlantis, this also serves as a little nostalgia - to remind how wonderful everything was then. This episode is a beautiful mix of all the things going on in both galaxies - wraith and ori.. stargates and supergate.. and ofcourse the hologram, what comes out is not hologram at all. I think this episode will have some huge impact of what will happen in future but I think Daniel missed the most important sentence what Morgana le Fay said just before she was pulled back.. But I think it is wanted this way.
Anyway, it was lovely episode, lot of happening, revelations.. answers and much much questions.
