So now comes the question of "what is to be done about Dandy?"
I had an idea for how they actually joined the team; Dandelion could be the most recent teammate to join, as their recruitment was actually the most recent attempt at their "first real mission" that they still have not had.
Julian, with all of his hacking and connections to major corporations, heard about the villain (maybe The Light? Who knows) attack on the STAR Lab, and saw "extraterrestrial missing and presumed escaped; capable of replicating and replacing any living thing; considered an extreme risk to local population," and from there decided to mobilize the Renegades.
They went all out, magic wards, super-scientific tracking, battle plans and tactics out the wazoo, and then when they get to Fawcett City and track the alien down, they just go "Hi, I'm Dandy, can we be friends?" And from there they join the team.
What do we think?
