"Somewhat." Ken watches Wormmon sleep with a smile on his face, knowing an answer like that requires clarification. "This isn't my first time in another world. I traveled to Wormmon's world three years ago, but we've only been able to stay together recently."

Now that he has the ability to travel worlds at will, and take Wormmon back with him. Or, well, had. He doesn't have his Digivice with him and has heard it doesn't work anyway.

That's still an incomplete answer, however.....Ken considers his words. Something this emotional is hard to pin down with his preferred precision. "Wormmon is what's called my 'Digimon partner'. He's always been waiting for me."

You could probably raise plants off the warm fondness radiating from Ken right now. "And in my own way, I was waiting for him, too."
