S05E06: Bloodlines

Nightcrawler gets a mysterious message. He is informed that his birth mother (whom he never knew) is in trouble. He turns to the X-Men for assistance. Jubilee is baffled that Nightcrawler wants to help the mother who abandoned him -- she has never known her birth parents and feels pretty hostile toward them, whoever they are. Nightcrawler admits there has been pain, but his faith in God has helped him overcome her rejection. The plot thickens when one of the team members recognizes Nightcrawler's mother's voice.
