Starting with Blackarachnia, her issues would be immensely helped by having someone come back for her. Her self loathing is very tied to her abandonment so just having another person to care about her and to care for would stop her thoughts of "I can only rely on myself" before they took root.

Arachnus in my au (Not that I have introduced him yet) was too trusting of the Autobots. Unlike Blackarachnia he didn't believe the Autobots would hurt him and so turned to them for help and was consequently captured and tortured- which now wouldn't occur because Blackarachnia knows better.

For Sentinel Prime (He needs a spider name so bad) he has a lot of the risk factors of Blackarachnia and Arachnus as he spirals a lot with power and really needs someone to keep him in check. Which the two of them can do in spades.
