Episode 7:   Ed has gained his National Alchemist title. He now has access to the state library, which contains many texts about alchemy. He hopes to find clues about the Philosopher's Stone, which gives an alchemist unlimited power, while ignoring the "fair trade" rules. Ed and Al still reside with Tucker and Nina. Tucker's annual review approaches, to gague whether or not he retains his National Alchemist status and funding. Tucker is very nervous about losing his grand home, for he is expected to top his previous feat of creating a chimera that speaks. After much shiftiness, Ed discovers that Tucker has turned his daughter and dog into a new chimera. Nina/Alexander experiences much pain in their new form. Ed decides to revert them both to their original states but is halted by the manic ramblings of Tucker, who plants seeds of doubt into Ed and his confidence in his abilities.   Tucker had been the protege of an army commander who goes by the alias "Metalfist." Metalfist shows up to take the new chimera away for research. Ed objects, gets knocked out, wakes up and breaks Nina/Alexander out of the truck they were being transported in. Nina/Alexander runs away before Ed and Al can catch it. For the second time, we see the mysterious man (Scar), who runs into Nina/Alexander in an alley and frees it from its pain...by destroying it, without the help of an array. Scar mutters about removing from the world all abhorrances of alchemy and those who create the abhorrances. Ed and Al find Nina/Alexander's remains, with no sign of how this tragedy happened.   In this episode we learn:   -army officers seem to have a thing for getting credit for finding remarkably talented alchemists -desperate alchemists lie to get what they need or want -Ed feels doubt -Scar is crazy   Note: we see Ed write a letter with his left hand (and its in English!). Previously, before he had his automail, he wrote with his right hand. It looks safe to guess that delicate actions like writing cannot be handled by his automail right arm.
