requiem be a good end to season 7 with a few thing i would have prefer a little different . i like the idea of return to the case of billy mile and reminisce a little on the pilot episode . a i watch the episode i can not help but think about all the thing that mulder and scully have learn in the past seven year about the alien race . it especially hit when they begin talk about have see the toxic blood before a if it be old news and scully explain it to billy . i put myself in billy shoe and wonder if they know that last time i saw them or if they have learn about it since then . i also be very glad to see marita covarubias and alex krycek again . i love that scene when mulder and skinner and these two be in mulder office and he try to attack krycek and then they be stand around talk when scully walk in . her face say what the hey be go on here mulder . anyway probably the one thing that i do not really like be how they put the whole thing in one episode . i wish they could have do it a a two parter . but oh well . chris carter mention in the special feature that he do not even write the end of the episode until they be almost do filming to avoid let out any spoiler . i respect him for that . i give this episode a positive .
