Sorry I haven't posted in a while, I've been a bit busy.

Anytime someone incorrectly suspects someone of doing something wrong, one is supposed to ask them for mechila, and in addition give them a bracha. The source is yesterday's daf (these pages have so many words, we're a day behind).

It is learned from Eili, when he suspected Chana of davening while drunk, and realized his mistake, he said, "Go in peace, and may Hashem give you what you seek."
