how does lear change when he regains his sanity?

Lear feels "out of it". Lear wakes and Cordelia addresses him. Lear feels awakened from the grave and wishes they had left him. Very drowsy at first, Lear thinks Cordelia is a spirit and then realizes he should know her and Kent (disguised) but has difficulty putting his memory together. Finally he recognizes Cordelia, to her delight, but thinks he is in France. The Doctor advises them to give Lear his space so Cordelia takes him for a walk.
