Is this the same person?

JIMENA They could be, and they have often been confused. In fact, they are the Lobillo brothers, Cayetano and Juan. Needless to say (so why do we?), they are twins. Prosp has known them for over 20 years and he still can't always tell which is which. Cayetano owns and runs Servijisa, in Estación, and Juan is a painter of both kinds, de brocha gorda (wide brush) and de brocha fina (fine brush). Can anyone tell me which is which in this pic, 'cos I can't?
