Supergirl and Reverend Howell approached Silver Banshee on the streets of Metropolis. They glared at her as she stood by one bank.
''You won't rob banks this time,'' Supergirl informed Silver Banshee while the latter scowled at her. She wondered if she was going to run any errands at all. Her eyes flew open as Silver Banshee's Death Wail knocked her down with Reverend Howell. She winced as she tried to get up.
Supergirl saw Silver Banshee's smile before she fell on her side. Glaring another time, her eyes were still on Silver Banshee until she went into the bank.
