In about 1970, Mickey, the son Mrs. Johnstone kept, meets Edward, the other twin, by chance, and after learning they share the same birthday, the two boys make a pact to become blood brothers, with Mickey calling Edward "Eddie". Mrs Johnstone finds them and sends Eddie away, telling him not to come round again or else the "Bogey-man" will get him. Later in the day, Mickey goes to Eddie's house, but Mrs Lyons throws him out when she comes to the realization that he is Edward's separated twin. She and Eddie argue on the subject, and Eddie swears at her. Mrs Lyons slaps him and immediately regrets her reaction. She realises that he has learned to swear from Mickey.
Bad Blood does attempt to add something new to the mythos by adding a new villain tied to Wade's past. It's a noble effort, especially considering how few great, recurring rogues Deadpool has relative to his long shelf-life. But this character fails to leave much of an impression. He isn't terribly remarkable from a power standpoint, and the flashback sequences never explore the shared history between the two characters in sufficient depth. In general, this book doesn't make great use of its roughly 100-page length. Most pages feature few panels or word balloons, opting instead for flashy splash images or giant head shots.
