Trial and Error was an exceptional episode of Supernatural. I really enjoyed watching because the story was swell written and very entertaining. There was also some great character development for both Sam and Dean. kevin is pushing the limitations of his body and mind in order to translate the tablet and though he has done good so far I fear for his future. Ellie's role was somewhat predictable but still awesome nonetheless. It what's intriguing to see the conflict between Sam and Dean as to who would perform the tasks required. I liked how everything played out and I certainly look forward to watching what happens next!!!!!!!!!
