The hug was unexpected, certainly, but not entirely unwelcome either. Jeremiah was hardly someone who was stand-offish, by nature. Not that long ago he'd moved through his social circles without much thought given to touching someone on the shoulder, or reaching over to give them a squeeze. He was a physical person by nature, and so hugs and touch had been a constant, and if anything, he hadn't had enough of either recent. With a quick smile, he brought his arms around Wren and gave him a quick one back.
"And you're quite welcome, I hope it'll help you stay warm."
