Have them be there?

Or have the Avengers dispatch them. Alternatively, we could have ARGUS kidnap Logan in order to research his healing factor, and then he runs into Starfire and the rescue team there?

Mainly just thought I could use the mission as a way to introduce characters.

They're unaware of his perhaps, so perhaps they find him locked up rather than him finding them?

Or he breaks out when their raid causes a distraction, then they run into each other.
