Whatever you were expecting, it was not him in a full-grown beard.
He went on a mission with the Titans, having to leave Blüdhaven for a few months. On the trip, his beard ended up growing out as he couldn't exactly find time to shave on a world-saving mission. He usually shaved at the first sight of a hair sprouting out, but maybe it was time to switch it up. After all, a little change never hurt anybody.
"Do you like it?" He was honestly a little proud of it. "Everyone else is telling me to shave it, but c'mon, it isn't that bad! ... Right?" He said, looking at himself in the mirror. "It's different, but different can be good. Look, even Haley likes the beard!" Haley couldn't exactly voice her opinion considering, well, she's a dog.
"Okay, it's a little itchy, but that's fine, that's very much fixable," he continued as he awkwardly began to scratch his beard. He obviously was more suited for the clean-shaven look, but he probably won't admit it. Even though he secretly agreed.
"Anyways, I think it's a good look." He grinned, putting his hands on his hips. Knowing him, he was going to get sick of it after a day or two and shave it right off.
