Their ID shows them to have the same last name, and they can probably dig up other documentation to prove their case. B has no such documentation, his last name doesn't match, etc.
No, you don't need to have the same last name to visit your sick partner, but when people start accusing eachother of lying, it will sure help.
Asserting counterfactuals is the short track to a loss. I encourage you to think through the ramifications of a situation or consult some case histories rather than just documenting your reflexive response.
