SUPER late welcome, apologies. I'm Zed, with Five here from The Umbrella Academy. He's much older than he looks, is a jerk, and doesn't socialise. In turn, I unfortunately know absolutely nothing about Irene Adler at all outside of your blurb and will endeavour to learn. Five is too smart for his own good, finds socialising boring (and not for the usual reasons), so on that alone he and Irene might get on well. But you never know!
