I don’t know if Juno knows this, but his family needs him as much he needs them.
And sure, there’s definitely the immediate concern of “everyone else was captured except one (1) thief in an undisclosed third location, time to stage a rescue mission” kind of need that falls to Juno now by questionable luck, with Jet’s heartfelt words about faith. Before that was the interrogation, when Juno had an advantage because he knew Sasha and because he could use that clever mind of his to make a plan in the same room as her, with her listening. He is a capable member of this team.
He is also a part of this family. When Nureyev handed him the journal, it was to get him out of bed - to get him interacting with the rest of the Carte Blanche in an attempt to pull him out of a low mood by putting him in the path of people who care about him. But everyone he talked to confided in Juno, too: Vespa asked him about trust in a relationship, Jet asked to sit with him while they considered their next step together, Rita had worries about the possibility of being alone soon, Buddy let off nerves from her wedding day. He’s as much a support for them as they are for him.
I’m not sure Juno realizes that. If he looked back on those conversations, I’m not sure he’d see more than the way they helped him; part of that low mood was because he didn’t have something to do for the wedding, and I wonder if that’s just a smaller example of Juno not seeing how he contributes. But I hope he has the chance to know that it’s more than necessity and usefulness that makes him important. I hope his family has the chance to tell him.
(And I hope the one, noticeable outlier - the one who hasn’t been confiding much, who didn’t talk to Juno before the wedding because he was using that time to remove every hint of himself from the ship - has the chance to let Juno, and the rest of them, in.)
