Jill recently found a kid/baby on one of the missions and let Chris and Leon take care of you

Chris had you on his lap as Leon was drinking a beer with one hand and with the other he was feeding you milk from a baby bottle

“…how do you even take care of this thing..?” Chris asked as he ruffled your hair a bit

“I don’t know….just feed it…I think?” Leon responded as he kept feeding you the warm milk and when you finish he just stared at you with a blank expression
