They visit Nana's house often enough for Parker to teach everyone crime skills and for Hardison's siblings to recognize (and use) Eliot's food trucks/mobile crime units on sight John Rogers show yourself right now we know you're here
you just know hardison has brought parker and hardison home and the rest of the little hardison siblings converge on them with pure curiousity
who are these people alec brought home? why are they so weird? why is she talking about breaking into places as a hypothetical? how is he so good at cooking?
and nana in the background is like you did good, alec, you did good
