oh with the motorbike, i didn't mean to say 'where did he keep it?' (but getting a bike up stairs in the tardis must be tricky), but the sudden 'it also drives up walls because the plot needs it to' ability that just came out of no where seemed like a random jump too far. and i couldn't think of a quick way to say it properly
I thought it was really clever and fun. And perfectly in keeping with Moffat's sillier, more fairy tale style.
