Unfortunately the DWMSE annual roundup issues in the Twelfth Doctor's era are of a completely different style to the ones from previous eras. They have more information about the broad "year of Doctor Who" and much less info about the individual stories. DWMSE 39 rather unhelpfully just says that the boy is uncredited. Earlier DWMSE issues would have told us who he was. DWM 477, the issue that actually went out with broadcast of Listen is unhelpful on this point, as well.
