Joshua had recovered by the time Thomas and Reno/Oner had finished with the Heartless. By the time Thomas landed he was leaning against a nearby tree, looking a bit bored
"Next time the enemy had better be quality and not quantity but at least that was a good workout." he commented, though his eye remained on Thomas. Something about their 'leader' was bothering him still. Thomas never displayed any powers of Darkness, at least not to the extend that Joshua himself did. But Joshua could swear he still sense darkness from Thomas but again, it felt muted, like something was hiding it. If Thomas was having his own struggle with Darkness, he shouldn't try and fight it alone. Joshua knew this all to well.

~~ If he does have Darkness within him, I have to find it out before it consumes him. Flat out accusing him will do no good. Gotta test the waters first before letting the ship sail.~~ he thought before setting off with the others. He kept an eye on Thomas the entire time, hoping to see a chance to try and find something out and confirm or deny his suspicions.
