Do আপনি think the Doctor is wrong about what would happen to Donna if she remembered him and there travels and if so what do আপনি think the outcome would be?

hes right if donna remembers her mind would burn as shown in the end of time but luckily the doctor wouldnt leave his best friend without a defense mechanism oh gosh what a tear jerking line idk what would happen though if donna sees the doctor and she remembers him whether she still have that defense mechanism অথবা not maybe it wont be safe?? idk sorry but one things for sure i want her back for the 50th
