I'm looking for advice on when to have a wing come into the set I've opened. After opener and I'm into a DHV story/routine?

I was thinking I should accomplishment intro him (Prior to his arrival. Example: "Yea, my good friend Jason is here, he's getting drinks now, but he's a great guy etc.. etc..).

Also, we're both new, but he is behind my level and comes in with low energy (we're working on it). I feel like his presence might be a DLV, would I maybe better solo until he gets his game up?

Any advice on how to weave him into an opened set would be greatly appreciated.
