2.5 year old repeating random phrases

Hi everyone. I’m a little bit worried about my 2 and a half year old son. He has recently started repeating random phrases and sayings from the TV and other people’s conversations. Last night I said I was gonna cook tomato soup, and after eating it, he said “the fresh tomato and basil soup was really good”. He seems to repeat certain things exactly how I said them and it surprises me. He is also constantly shouting out phrases from his favourite TV shows and movies, and he is obsessed with shouting out “and beyond”! I’m worried as he is suddenly showing this behaviour and I read this may be a red flag for autism. His development has always been normal, and we haven’t had many problems. Should I really be worried?
