No questions are dumb---unless they aren't asked.
You're right on the first and have no need to fear on the second.
Except for swarming season, If a hive raises more than one queen, the first one out will eliminate her potential competitors while they are still confined to their cells. She nibbles away at the base of the still closed queen cell and kills her with a sting. The bees clean away the remains.
However, once a mature virgin queen has emerged successfully from her cell she's got it made. Even when she goes out on her mating flights, she's always accepted back in the hive with no resistance---more correctly, she's welcomed back into the hive by the bees that were anxious while she was away.
