Felix should grab a gift grow some massive ⚽️🏀s and pretend to be that fake lover of hers. After all she will trust him since he saved her the night before. Just a thought.
There’s no way in hell Parker is there to kill her. Does not sound like the infamous Parker. Maybe threaten her and make her feel like an ant under his military boot but not kill her.
Felix should make sure Parker doesn't see him or even smell him around. Parker is always alert so just sensing an unfamiliar presence will get Felix in trouble
