The Wise Sovereign does not expect Angel to bring surprises; as long as a "change" is brought about, even if it is a detrimental one, he is willing to accept it.
The current remnants, the present Goddess Her Highness, and his current self are like a fixed axis wheel, severely internalized. With his ability, even if he could pry this axis wheel, he is unable to do so... due to rules and promises.
Therefore, if an outsider could pry this axis wheel, even if not heading in a positive direction, the Wise Sovereign believes that with his strategic acumen, he can turn the tide. The worst result would be resetting this severely internalized axis wheel. And resetting means starting everything anew, a new decision-making process during which the Wise Sovereign has the confidence to break this internalized system.
