Jamaal was used to this type of heat. Even before his powers really activated he had gotten used to this type of heat simply from living in Arizona; in fact, he was actually a bit more comfortable in this type of weather. He was in a pair of shorts and a Fairy Tail t-shirt knocking a soccer ball down the hall on his way outside when he saw the new guy having a bit of an issue. "Need some help?" He offered, peering into the room. He knew better than to just go and help someone who had that kind of injury.
Some people with broken arms were willing to accept offered help, some were the type that wanted to be waited on hand and foot(as this guy had not already gotten someone in to help that was doubtful) and some were too proud to accept help and often even got upset with those who tried(Jamaal usually became one of these types when he was injured). He didn't want to offend the guy on their first meeting, so that was why he chose to ask first.
