just so that the surnames are cleared up once and for all, both 'the stone house' and the iplayer subtitles spelled april's surname as 'maclean', and i checked on the bbc 3 website and april's page doesn't open (it just redirects to charlie's), so there is no actual proof for mcclain. (sorry im really petty about these things)
Dear god, why must they confound us like this? Getting ridiculous. Someone tweet Patrick Ness!
