Stucked in Seeker escort quest

plz help. i have problems with the quest seeker escort .
just started the quest by escorting the dog(king) and got disconected . when i logged back the dog was missing and i got stuck in the quest . now both npc's(dep and sebion) are just sending me to each other and cant do anything (((((
1h trying to do different things but nothing helps

 

usually there should appear another ponny named king, and try to go with him once more. the same situation happened to me, but everything went well when i speaked once more with that.

 

i spoke five hundred times with both npc's and nothing happens

 

i abort the quest and after that i retook it. didn't wanted to abort it cuz i thought i will lose the quest (it happened before) but since i get no attention for so long i just did it .
fixed
