Question: Are Blaster and Soundwave in any way related like Sideswipe and Sunstreaker are? They transform into tape-playing devices, they both have cassette robots and so on, so does any one know the answer?
Answer: Alpha Trion seems to have created these two robots with special abilities concerning sound. As all Transformers received new Transformation Forms from the arc after their "sleep", it might have been intentionally from the arc to give them Transformation forms similar to their abilities. However it is not mentioned in the series.
Answer: Warren T. grabbed Tiger and told him he was fired. Tiger did eventually leave some time after that though.
