Well Ice has been a member of the JL, and then there's Zan from the Wonder Twins. However I do like the idea of him visiting Freeze while nobody's around to know. Maybe after we meet the JL proper then return to Gotham, when the rest of us go on a road trip to Metropolis or Midway or something... Archer can go visit Arkham Asylum posing as Freeze' nephew?
