One thing that COULD work, if Jhey's into it, is Wynonna could snag the Doctor during the fight when Little gets hurt, because that's going to be a HUGE deal for her and she's going to be screaming for looking for anyone she can recognize to help! So if they have an early-month meeting and she learns about his healing feat (which she obliquely knows about through Jopson) she'd yell for him specifically if she sees him anywhere nearby. One thought!
