this episode be important for several reason . 1 ) it establish that there be a demon war come and that the psychic kid will play a part in it . 2 ) it introduce the character of ava and who will come up again . 3 ) it bring gordon back on the canvas . 4 ) sam finally admit that he be hunt because he think it make a real difference in the world . 5 ) it reveal what john tell dean in in my time of die represent dean must either save sam or kill him . this be an important episode and you really can not skip it . hunt revolve around sam finally learn about john dying word back in in my time of die . apparently have some idea of sam destiny and john tell dean that one day he would have to either save dean or kill his brother . dean be confuse by what his father meant by that and and why sam immune to the croatoan demon virus and how his vision be connect to the yellow eyed demon . dean think that they should lay low . sam disagree . angry and scar he take off for the roadhouse leave dean behind . while he there and he get ash to find out more about the psychic kid . it turn out one have be kill recently and sam head off to investigate . sam soon meet up with a girl name ava and who say that she have vision of people death and just like sam . she see sam be blow up . she and sam begin investigate the other psychic guy death . dean arrives in town and just in time to stop gordon from kill sam . gordon kidnaps dean and explain that he on a new mission . he hear of a come war between human and demon . the psychic kid be suppose to be help the demon side . gordon try to trick sam into trigger an explosive device and but thanks to ava warning and sam survives . he and dean escape gordon and call the police so gordon be arrest . dean say that they should lay low and especially when they learn that someone at the roadhouse tip off gordon . but and sam insists that he commit to hunt now and that what the brother do make a difference in the world . meanwhile and ava vanishes and her fiancé be kill . the boys find trace of sulfur at her apartment and think she might have be take by demon . there be some good part to this episode . i like the scene with sam and dean discussing john . dean be try to explain thing to sam and but all sam can hear be that he might go evil . i think sam know that dean will try to shield him and that the only way he will ever get any real answer be to go out look for them . otherwise he could one day just wake up darkside and hurt his brother . it an interesting . and i like ava . she such a cute and funny little thing in this episode . she and sam be actually a good team and a they investigate the case . her line and can not you just leave town before you blow up . just make me laugh . and i always like gordon . he such a good villain because he believe what he do . when dean attack him in a blind rage and punch gordon and the two of them fight on the rooftop it really cool . the phone call where dean tip sam off with the code word funky town be perfect . and i like the trip wire go off a sam break into the abandon house . dean panic a he think that sam have be kill be incredible . when sam come into untie him and dean just grab at his brother and check him for injury and immediately head into kill gordon . but and dean leave the house when sam ask him to and because he trust his brother judgment . it sweet . one interesting feature of this episode be the question that gordon pose to dean . gordon be convince that sam be evil . an unclean anti christ type figure . he convince that he right in his quest to kill sam . gordon can sort of understand dean hesitance to get on board with the let kill sammy plan and see a sam his brother . but he also think that and a a professional hunter and dean should be able to understand the big issue here . he see dean a blind by emotion . so gordon asks what dean think john would have do . if sammy go evil and if john could stop him and would he shoot his own son . it an interesting question . john seem to have tell dean to do just that in in my time of die . but and realistically and john have to know that dean would never shoot sam . not for any reason . no matter what . before john tell dean that he might have to kill sam one day and he start cry and tell dean that dean be the one who would keep the family together . ( you take care of me and you take care of sammy . ) and that be also just hour after the event of devil trap and where john heard dean beg sam to not shoot john and stop sam from kill the yed once and for all . so in in my time of die and could john have really believe that dean would kill sam if it come down to the line . do he really want dean to . could john have do it himself . i just do not know . on the down side and we never do get any resolution on how gordon get the information on sam from the roadhouse . my favorite part of the episode represent ava at the psychiatrist office and act a a distraction for sam . i just remember that when i be a kid and i eat like 6 thing of pop rock and then drink a whole can of soda . you do not think that count a a suicide attempt and do you .
