Some citations:
Vana Parva where Drau laments to Keshav:
O Krishna, how could one like me, the wife of Pritha's sons, the sister of Dhrishtadyumna, and the friend of thee, be dragged to the assembly! Alas, during my season, stained with blood, with but a single cloth on, trembling all over, and weepigged to the court of the Kurus! Beholding me, stained with blood in the presence of those kings in the assembly, the wicked sons of Dhritarashtra laughed at me! O slayer of Madhu, while the sons of Pandu and the Panchalas and the Vrishnis lived, they dared express the desire of using me as their slave! O Krishna, I am according to the ordinance, the daughter in-law of both Dhritarashtra and Bhishma! Yet, O slayer of Madhu, they wished to make of me a slave by force! I blame the Pandavas who are mighty and foremost in battle, for they saw (without stirring) their own wedded wife known over all the world, treated with such cruelty!”
Vyasa's words before Swayamvar:
Ye princes of Bharata's line, that damsel of celestial beauty hath been born in the line of Drupada. The faultless Krishna of Prishata's line hath been appointed to be the wife of you all (bhavataa). Ye mighty ones (mahaabalaa), go therefore, to the capital of the Panchalas and dwell ye there. There is no doubt that having obtained her as wife ye shall be very happy”
Here's Arjun's reply aftee Yudhishthir suggests he marries Draupadi first.
O king, do not make me a participator in sin. Thy behest is not conformable to virtue. That is the path followed by the sinful. Thou shouldst wed first, then the strong-armed Bhima of inconceivable feats, then myself, then Nakula, and last of all, Sahadeva endued with great activity.
Now we all know that before this, Bheem-Hidimba marriage had already taken place. So in no way waa Arjun suggesting ONLY YUDHISHTHIR marries Drau but in all probability he is saying you marry Draupadi first followed by us. A polyandrous marriage.
Another quote from Vana Parva when Jayadrath abducts Draupadi;
https://www.sacred-texts.com/hin/m03/m03264.htm
I am the daughter of king Drupada, and people know me by the name of Krishna, and I have accepted as my husbands, five persons of whom you may have heard while they were living at Kahandavaprastha. Those noble persons, viz., Yudhishthira, Bhimasena, Arjuna, and the two sons of Madri, leaving me here and having assigned unto themselves the four points of the horizon, have gone out on a hunting excursion.
Are all of these interpolations? It's hard to accept that.
