Megatron kept his focus on the communications mech, listening quietly and keeping his questions to himself, rather then asking them and interrupting his friend. He can't even begin to imagine what the time had been like, though from the full description it sounded rather eventful.

He nods when Soundwave talked about coming here. It sounded to be a situation where he moved from one universe to another. Still he kept quiet, rather than interjecting his questions. Those could be gotten to once he had been told the whole story.
