[The color slowly drains from Marcus' face. That's... a lot to take in, for multiple reasons, and the words "I didn't want Riku to go down without a fighting chance here" cause his heart to constrict with painful sympathy. He'd feared much the same thing for Phil until the fairies had so graciously provided his medication - medication he knows Tenn has seen during the trials by now - but had they not done so, he finds he can't deny that he might have been willing to do the very same thing to help Phil.]

... that son of a bitch.

[It's the harshest language Tenn will have heard out of Marcus yet.]

If he tries anything while I'm around, he's gonna have to answer to me. That much is a promise.

[He doesn't know if he'll be able to keep it, but by god, he's going to try.]
