6)Arjuna - he was her friend. I will like to go with nora on this. She pretty much summed it up.
Arjuna
1 Dice Hall -
"Duryodhana, hearing Vidura thus speak, said,--'I am willing to abide by the words of Bhima, of Arjuna and of the twins. Let them say that Yudhishthira is not their master. Yajnaseni will then be freed from her state of bondage."
"Arjuna at this, said,--"This illustrious son of Kunti, king Yudhishthira the just, was certainly our master before he began to play. But having lost himself, let all the Kauravas judge whose master he could be after that."
2 To Krishna before he was going for Peace talk -
I thought that Suyodhana deserved death at my hands. What thou, however, O Krishna, wishest to do for thy friends is scarcely strange, although it seems inexplicable how the object In view is capable of being effected by either mildness or its reverse. Or, if thou deemest their immediate destruction to be preferable, let it be effected soon without further deliberation. Surely, thou knowest how Draupadi was insulted in the midst of the assembly by Duryodhana of sinful soul and how also we bore it with patience. That Duryodhana, O Madhava, will behave with justice towards the Pandavas is what I cannot believe. Wise counsels will be lost on him like seed sown in a barren soil. Therefore, do without delay what thou, O thou of Vrishni race, thinkest to be proper and beneficial for the Pandavas, or what, indeed, should next be done.'"

3 Krishna in Hastinapur about Arjuna -
“Then in that hall, while Krishna stood, the charioteer's son addressed her in the presence of her fathers-in-law saying, 'O Daughter of Drupada thou hast no refuge. Better betake thyself as a bond-woman to the house of Dhritarashtra's son.Thy husbands, being defeated, no longer exist. Thou hast a loving soul, choose some one else for thy lord.' This speech, proceeding from Karna, was a wordy arrow, sharp, cutting all hopes, hitting the tenderest parts of the organisation, and frightful. It buried itself deep in Arjuna's heart

4 Virat War -
Abandoning good breeding, thou hadst uttered many harsh words, but this that thou endeavourest to do, is, I think, exceedingly difficult. Do thou now, O Radha's son, contending with me in the sight of the Kurus, make good what thou hadst said before in disregard of myself. Thou who hadst witnessed Panchala's princess outraged by villains in the midst of the court, do thou now reap the fruit of that act of thine.

5 Drona Parva -
Thus addressed, Partha replied unto Kesava saying--'So be it. Even this should be done by me. Disregarding everything else, proceed thither where Duryodhana is. Putting forth my prowess in battle, I will cut off the head of that wretch who hath for such a long period enjoyed our kingdom without a thorn on his side. Shall I not succeed, O Kesava, in avenging myself of the insult, in the shape of dragging her by the hair, offered unto Draupadi, undeserving as she was of that wrong.'

There's Karna's vadh and in later chapters he blames himself for what happened to Draupadi in dice hall (Nakul or Sahdev do too), I don't remember the parva
