"Will this give an ET problems.? No." 8 letters N???T??E
nepotism seems to the obvious choice but the last letter E is part of "The Lion, the Witch and the wardrobe" which fits in every where else and should be correct.
No. 8 across "Get back from a reign of disaster" R???I? if that is "repair" then the third letter of the first clue is "P"
Sorry for complicating things!
