So it's like this

"If the fortified soul conjunction allows you to manifest your soulbonds' body parts, why shouldn't a fusion be possible!?"

Jason was just blurting out things, while Betty looked at him in confusion.

"I...was just joking…"

However, Jason couldn't even hear her anymore as his mind had already secluded itself, trying to make sense of what had just happened. 

The sensation of the fusion had been unique and his entire aura had changed due to Artemis' influence. 

Exactly the same could be said about his demeanor and combat style during the fight against the two God's Children. 

'Why did I suddenly merge with Artemis? Did something change about our connection, or did an external factor allow this?'

Jason was not sure what exactly it was, but his strength had increased tremendously after merging with Artemis.

The fusion was definitely something special, and worth researching. He would have done it if he just had enough time.
