(Selkie would probably make the most sense. Probably.
...
Would it be weird if Kal was still hovering over Selkie's shoulder even though both of them are already dead?)

Sonic put his hands up defensively. "Hey, didn't mean to offend you...!"
Knuckles glanced up again. "Just answer the question. He won't stop pestering you until you do." He advised before reaching for a few grapes.

(Nope not wierd after all they are best friends)(Only reason I thought Douglas is teacher, guide, knew Echidnas.)

"Sorry not answering the question." Ajal stayed stuborn.

(True, but Knuckles instantly dislikes most people with the word 'doctor' in their title.) (I dunno whoever you want.)

Knuckles casually popped a grape into his mouth. "Your funeral."
Sonic trotted over to Ajal. "C'mon.... you can tell me!"

(Douglas doesn't tell most people he's a doctor only that he is opposed to violance.)(Selkie would probally be best anyway I mean who doesn't love the free, fun loving otter?)

Ajal hit him lightly with the pillow as a warning.

(Certian badgers, appearently.)

Sonic simply zipped over to the other side. "C'mon. What are you thinking?"
Knuckles frowned. "I tried to warn you."

(True)

Ajal walked outside.

Sonic was practically on his elbow. "What're you thinking?"

Ajal hit Sonic over the head with the pillow.

Sonic didn't seem to mind much. "Just tell me dude." He insisted.

Ajal ignored him.
