Queen Elizabeth was displeased he had not yet found some way to "shorten the life" of his prisoner. His loyalty was unquestionable, as was his honour. His response was blunt and immediate.
The most powerful nobleman in England raised a reasonable proposal with the Queen's own council. Elizabeth did not find it reasonable. She found it useful, which is a different thing entirely.
She crossed into England in a fishing boat at twenty-five and wrote to her cousin asking for help. She would not leave for nineteen years. She would not leave alive.
