Strange doesn't want to admit it, but Steven's right. Both about the fact that they shouldn't be watching this and also the fact that they're going to probably fight their friends. He gets one last look in at Lambert before, with a wave of his hand, the spell vanishes and the water reflects their faces again.

There's a pause before Strange actually answers Steven's question. "Most likely." At least, he's certain he will. What's the use of training a soldier if you don't have them fight someone?

"I can dispel certain types of fae magic," Strange starts to explain, seemingly out of nowhere. "If we're in the same area and I'm myself, I can try to disenchant you. However, if I am also enthralled, I know I won't be any use."
