Arjean didn't really catch the bag. More like the air shot it down at the floor so they wouldn't get hit. Every time something was thrown at them and they attempted to catch it, they always panicked, caught it, then awkwardly dropped it. It was easier to have the air handle it.
While helping themself to the bag of candy, Arjean grimaced at how rough Junchi was with his words. That isn't to say they disagreed with him, but Junchi tended to be blunt and pushy with his intentions, good or bad. Aluin and Fulger were both nervous kids. Arjean could relate to that. That's why they felt it was their place to try being a buffer to Junchi's aggressiveness.
"Getting sick is scary... but blankets make me feel comfortable sometimes. Like I'm being hugged and protected from scarier things..." This would probably be followed up with Aluin saying being comfortable or warm or hugged is scary, but those were the best words of comfort Arjean could think of.
