How did Loki escape Lamentis?

Loki uses a TemPad to teleport himself and Sylvie away. They arrive at 2077 Lamentis-1, a moon that is about to be crushed by a planet, but neither can escape due to the TemPad having run out of power. They agree to work together because Loki has magically hidden the TemPad while only Sylvie knows how to recharge it.

How did Loki and Sylvie cause a nexus event on Lamentis?

What happened between Loki and Sylvie to cause a Nexus event? In episode three, after their TemPad broke, Loki and Sylvie were left stranded on Lamentis-1 facing an apocalypse with no way out. However, they touched hands and shared a moment before what looked like inevitable death, and this caused a Nexus event.

Why did Loki and Sylvie cause a nexus?

On the other hand, Lokis are supposed to be narcissistic and only care about themselves first. Loki and Sylvie’s connection had them caring about one another and going against the “Loki script” while on Lamentus-1. So that too could have equally caused the Nexus event.
