this arc will feature a game of identities... a risky plot indeed for the guionists who must deal between the mistery of Obi-Wan new role and the obvious leit motifs, the series has established for Kenobi.
The way Obi become the hunter, a surrealist alternative to cosmetic surgery and more bizarre when he swallows the communicative device to mimec the killer´s voice.
They could have fancy this chamaleonic method to other character, is a wrong mixture of Zam Wessel skills with Kenobi capabilities. The changes of a character don´t need to be always graphic, more interesting will be a moment when he could have turned to a more aggresive manner, intead of his calm way.
To sinthetyse I don´t like the idea of a main character becoming a plasteline guy.
