During the Battle Nexus Arc, Leo is being healed by the healer with Usagi and Don watching the process. Don unaware of what's going on comments on the procedure.
Don: What's with the Volkun mind meld?
Usagi: Volkun mind meld?
Don:...
What is the healer doing to Leo?
I like that delivery there isn't a lot of times when 2k3 Don is snarky.
