"Grey?!"
Rex was petrified from surprise but Grey was not as the massive Dark Mist Spider ran into him. Despite becoming a tenacious survivor already, Grey still retained that inherent loyalty and love that it had for its master.
The massive Spider engulfed Rex completely in a hug that almost suffocated him. Grey's hug was not exactly that of love, but to check if he was injured.
It was only after confirming that his master was uninjured and was fine did the Dark Mist Spider finally calm down and stood beside Rex just like old times.
Once Grey calmed down, it finally became Rex's turn to become emotional.
Though it was not supposed to be, as his first transformed beast, it was inevitable that after going through many battles and surviving together, he already developed a lot of emotions towards it.
Rex patted one of Grey's legs before hugging it tightly.
