Well, adopted or not, he was my father. By technicality anyways. [A faint shrug- he knew Laufey's opinions of him, and honestly didn't care much. If keeping his name irritated the Jotun king, well Loki never professed to be a saint.]

Thor's much better. Less formal and stuffy. [Loki is likewise reminding himself of the multiverse. That this Thor likely had reason to be startled by open emotion from him. It eased some of the hurt, at least for now, and Loki relaxed a bit again, expression less cautious once again. He'd just have to prove himself. He could do that.]

The Old Man I used to be he... was nearly the ruin of Asgard. Led enemies to her gates for a battle he intended to push the realm to it's rightful place once again. But he underestimated the enemy. Underestimated the power of the Void that was used to destroy the realm instead, and strove to stop it. Used the Norn Stones to infuse Asgard's defenders with additional power, before the Void ripped him apart for it.
