Heals Nobleman's Son
A. D. 27
Cana
It seems a big point to Jesus that the nobleman did not get whatever concerning himself (Jesus) that (I assume) the nobleman heard at Jerusalem.
Jesus told Nicodemus to look to him (Jesus) for eternal life in the Kingdom. Possibly he was telling that to all who would listen.
But anyway, the main reason for Jesus to heal the sick was to gain credence for his "born again" message, not to show his mercy.
Then said Jesus unto him, Except ye see signs and wonders, ye will not believe.Joh 4:48

Then enquired he of them the hour when he began to amend. And they said unto him, Yesterday at the seventh hour the fever left him.Joh 4:53
So the father knew that it was at the same hour, in the which Jesus said unto him, Thy son liveth: and himself believed, and his whole house.Joh 4:54
This is again the second miracle that Jesus did, when he was come out of Judaea into Galilee.
