* They're rare, but there are moments where Gotrek lets slip a little bit that he values Felix. Most notable is that nearly every time a dwarf trash talks Felix, Gotrek is quick to jump to his defense.
** The reverse as well. As an example in Elfslayer Felix believes for a moment that Gotrek may have actually died and frantically scrambles to him to find that he hasn't. Despite still being on a collapsing Black Ark and under insane threat from all corners Felix's internal monologue concludes "Well, that's all right then."

!!Trollslayer
* When Felix is talking to a little girl the rescued and she calls him brave. It makes him all flustered.
** After years away and losing friends or seeing them hurt badly, they see the same little girl all grown up and following in their asskicking, name taking, chaos slaying foot steps. Her first words when she reconizes them? "My heroes!"

!!Orcslayer
* Gotrek reconciling with Prince Hamnir after decades of estrangement from each other.

!!Kinslayer
* Snorri's death, albeit mixed heavily with TearJerker. He has spent so long unable to remember why he became a Slayer in the first place that he is sure that when death does find him, he will be denied atonement and his spirit will spend eternity in limbo. His memory finally returns, and he asks Gotrek to be the one who kills him. Despite Felix's protests, Gotrek obliges, and when Felix forces himself to look, the last thing he sees on Snorri's face before Gotrek delivers the killing blow is an expression of peace which Felix never saw before.
** This is fulfilled in ''Realmslayer'', when Gotrek finds Snorri's spirit and apologizes for having to kill him. Snorri makes clear that he holds no grudge.

!!Realmslayer
* The sheer strength of the bond that Gotrek and Felix develop over their adventures together is incredible, especially when you recall that dwarven opinion of humans in the Warhammer world is so low that the dwarf word for "human" is literally a derivative of the word for "shoddy work". It reaches its peak in ''Realmslayer''; learning of the Stormcast Eternals, Gotrek becomes convinced that he'll find Felix if he goes to their stronghold in Hammerhal, absolutely dead certain that Felix would have been selected for the Reforging. This thought essentially rekindles Gotrek's will to live, giving him something to hope for.
** Towards the climax of ''Realmslayer'', the fyreslayer battlesmith Broddur learns that Felix was a poet, and asks Gotrek what makes the dwarf so certain that Sigmar would have reforged Felix as a Stormcast. Gotrek practically roars out his reasons, showing just how much his manling meant to him.
-->'''Gotrek:''' ''"He slew a Chaos Dragon, storysmith. Have you ever done that? He followed me to the darkest places of the Old World, all the way to the Chaos Wastes, and back, all on the strength of his word alone! Twenty years, we traveled the world, before I released him from his oath so that he might go home and be wed! [[TrueCompanions And even then, he managed to be there beside me at the very end!]] If there's a hero amongst the Stormcast Eternals worthy of even polishing the manling's mail, then I'll [[SeriousBusiness cut an]] '''[[SeriousBusiness inch]]''' [[SeriousBusiness off my beard!]] You, storysmith, aren't yet worthy to speak his name -- not until you've notched your blade on a Chaos Lord or ten!"''
* Another moment from ''Realmslayer''; during the third quarter of the story, when traveling in the Realm of Shyish, Broddur spies on Gotrek to learn where he's been creeping off to at night... and discovers he's been in contact with the ancient ghost of Gotrek's oldest friend, Snorri Nosebiter. The two slayers reminisce with what the narration itself describes as the comfort of old friends who see each other every day. The kicker has to be when Gotrek actually ''apologizes'' for killing Snorri, who in return makes it clear that he holds no grudge.
* In the Age of Sigmar short story "One, Untended", Gotrek ''immediately'' perks up from a bout of over-indulgence induced vomiting (actually the side-effect of being fed enough poisons to kill a giant by his treacherous Witch Aelf companion) when he hears a nearby group assembling to try and rescue a lost child, who has strayed into a reputedly haunted tunnel system, and offers to help them in his own surly way. He ends up successfully saving the infant, and the last shot of him in the novel is him holding the babe in his arms and even softly singing them an ancient dwarven lullaby. Though he gruffly denies it, instead making a lame excuse, it's obvious he was motivated because he wanted to help. This gets extra touching if you're familiar enough with Gotrek's backstory to know that, in a long-lost age, he too was a father...
