It's tricky. See, you get a token. Then, you place that token above the condition's card, you know, the one that's being borne by a companion? Yeah. Then, you leave it there. And that's it!

LOL
Seriously, though, I don't REALLY see a problem with it, might be a "little" clunky as a design, but that's about it, it can totally be pulled off. Like stacking cards on cards borne by a companion, which is something I did constantly with DCs.
