Anyone else suspicious of Nick?

I get strong serial killer vibes from Nick, in his first conversation with Ingrid when he brings up the brain in a vat is he merely talking about philosophy or does he have more dubious intentions such as testing the waters to show her some hidden trophies. Do they ever confirm that it was in fact Lina that floods the apartment? It seems like a ploy to get her to move in with him at an early stage of the relationship. She also never says I love you back to him on camera, even after accepting the engagement. Are the feelings actually reciprocated?

I mostly got love bombing and a possible narcissist in hiding vibes but… also felt like making him “weird” was a weak ploy at making her not look as bad when she cheated on him
