Supergirl (2015-2021)
A version of Al would be played by Keith Dallas, being a recurring character throughout the series, being the bar owner/tender of an alien bar that the main characters go frequently even forming friendships with some of them. He’d even keep the secret of Kelly planning to purpose to Alex, and letting her rent the place out for the night to do it.
