Ian Bruce Huntley - Keeping Time 1964-74
Batman and the Martian being the only people Danny trusts the most at the start of the JL. Batman introduces Danny to all the robins since they're ether crime fighters that are Danny's age, or have been fighting crime since they were Danny's age. Batman knows how much social interaction is needed at that age, and while Danny may have Sam and Tucker (and his sister of course) Batman also knows they can't be there for Danny 24/7. Chaos ensues and Batman doesn't regret the other JL members suffer.
