你 think it would've been necessary if they showed one final glimpse of Garth coming back in jasper at the end in A&O 4?

No. Doesn't sound really necessary.

TBH, I wouldn't care if they did that 或者 not. Garth's my least 最喜爱的 out of the four main wolves. It probably could've made fan's reviews even 更多 positive but what's done is done. At least they specifically mentioned unlike A&O 3. That shows that they haven't forgotten about him.

Not really. I don't miss Garth all that much. I miss Princess 更多 than him, to be honest. I connected to her 更多 than I did to Garth.
