Just before Henry's death, reformers became dominant faction at court.
The indiscretions of Henry Howard, Norfolk's son, led to his execution and the imprisonment of Norfolk.
Norfolk's son was meant to have claimed that he should be regent for Prince Edward and even hoped to become king if Edward died.
Gardiner was also in trouble with Henry over exchange of Church lands and execution of his nephew Germaine.
At the same time, the reforming faction under the Seymours, Dudley and Cranmer was doing well.
Seymour and his Protestantallies controlled the Privy Chamber and thus access to dying Henry.
Seymour's control of royal household also allowed them access to Henry's will and would allow them to disregard Henry's wishes about government for Prince Edward.
